  • DC Servo Motor Modeling
    MODELING DC SERVOMOTORS CONTROL SYSTEMS TECH NOTE © Dr. Russ Meier, MSOE INTRODUCTION A DC motor is an actuator that converts electrical energy to mechanical rotation using the principles of electromagnetism. The circuit symbol for a DC motor is shown in Figure 1. + Va M - Figure 1: Circuit symbol for a DC servomotor The learning objectives of this technical note are: 1. Draw the equivalent DC servomotor circuit theory model. 2. State the equations of motion used to derive the electromechanical transfer function in the time domain and the s-domain. 3. Draw the DC servomotor signal block diagram. 4. Derive the DC servomotor electromechanical transfer function. CIRCUIT THEORY MODEL The circuit shown in Figure 2 models the DC servomotor. Note that an armature control current is created when the armature control voltage, Va, energizes the motor. The current flow through a series-connected Ra La + + Tm Va Vb R θ m - - Figure 2: DC servomotor circuit theory model armature resistance, an armature inductance, and the rotational component (the rotor) of the motor. The rotor shaft is typically drawn to the right with the torque (Tm) and angular displacement (θm) variables shown. The motor transfer function is the ratio of angular displacement to armature voltage. Figure 3: The DC servomotor transfer function EQUATIONS OF MOTION Three equations of motion are fundamental to the derivation of the transfer function. Relationships between torque and current, voltage and angular displacement, and torque and system inertias are used. Torque is proportional to the armature current. The constant of proportionality is called the torque constant and is given the symbol Kt.

  • Direct Drive Dc Torque Servo Motors
    DIRECT DRIVE DC TORQUE SERVO MOTORS QT- Series Rare Earth Magnet Motors DIRECT DRIVE DC SERVO MOTORS The Direct Drive DC Torque motor is a servo actuator which can be directly attached to the load it drives. It has a permanent magnet (PM) field and a wound armature which act together to convert electrical power to torque. This torque can then be utilized in positioning or speed control systems. In general, torque motors are deigned for three different types of operation: » High stall torque (“stand-still” operation) for positioning systems » High torque at low speeds for speed control systems » Optimum torque at high speed for positioning, rate, or tensioning systems SUPERIOR QUALITY With the widest range of standard and custom motion solutions, we collaborate with you to deploy rugged, battle-worthy systems engineered and built to meet your singular requirements. Kollmorgen provides direct drive servo motor solutions for the following applications: » Weapons stations and gun turrets » Missile guidance and precision-guided munitions » Radar pedestals and tracking stations » Unmanned ground, aerial and undersea vehicles » Ground vehicles and sea systems » Aircraft and spacecraft systems » Camera gimbals » IR countermeasure platforms » Laser weapon platforms QT- Series D irect Drive DC Servo Motors Advantages of Direct Drive DC Torque Motors Direct drive torque motors are particularly suited for servo system applications where it is desirable to minimize size, weight, power and response time, and to maximize rate and position accuracies. Frameless motors range from 28.7mm (1.13in) OD weighing 1.4 ounces (.0875 lbs) to a 4067 N-m (3000 lb-ft) unit with a 1067mm (42in) OD and a 660.4mm (26in) open bore ID.

These applications usually have dynamic considerations that require position-time closed loop and high accelerations. When accelerating large loads, permanent magnet servomotors can work with very high load to inertia ratios and still maintain performance requirements. Having a lower inertia typically will allow for less permanent magnet motor can result in a greater torque energy wasted within the motor. Torque (τ), is the density than an equivalent induction system. If size product of inertia (j) and rotary acceleration (α). If you matters, then perhaps a system should use one require inertia matching, ½ of your energy is wasted technology over another. Speaking of size, the inertia accelerating the motor alone. If the inertia ratio from ratio can be an important figure of merit should motor to load is large, then control schemes must be dynamic needs arise.

  • Selecting the Proper Cables for Your Stepper Or Servo System
    Selecting the Proper Cables for Your Stepper or Servo System Kollmorgen 540-633-3545 [email protected] www.kollmorgen.com Engineers devote a lot of time and effort designing highly efficient, reliable, and economical stepper or servomotor positioning systems. They select a motor, a controller, appropriate feedback circuits, and an amplifier to satisfy the specific motion system’s needs. Unfortunately, however, the signal and power cables connecting the components are often neglected until the project is nearing its end or worse yet, handed off to an electrician who lacks the proper training. Overlooking critical cable selection factors can deliver a system with lower than expected accuracy, frequent failures, low immunity from electromagnetic interference, and adverse affects on neighboring equipment. BASIC CABLE CONSTRUCTION Cables are designed and manufactured with characteristics intended to service a specific application for peak performance. Each element in the basic cable construction plays a unique role. All cables contain some or all the following elements: single or multiple conductors of proper ampacity, insulation with appropriate voltage breakdown specifications, an overall shield or multiple shields for individual conductors or pairs, and a jacket to protect the cable from mechanical, chemical, and environmental influences. Additional cable elements might include a drain or grounding wire used with foil shields, binding tapes, embedded steel-support wires, and fillers to give the cable a uniform circular, cross- sectional shape. SELECTION CRITERION Cable selection begins with characterizing the operating conditions that affect the cable during service such as temperature, moisture, chemical exposure, abrasion, flexing, and expected life. The proper type and thickness of the insulation selected depends upon working voltages.

  • Torque Control for DC Servo Motor Using Adaptive Load Torque Compensation
    SELECTED TOPICS in SYSTEM SCIENCE and SIMULATION in ENGINEERING Torque Control for DC Servo Motor Using Adaptive Load Torque Compensation CHANYUT KHAJORNTRAIDET JIRAPHON SRISERTPOL School of Mechanical Engineering, Institute of Engineering, Suranaree University of Technology Address: Nakhon Ratchasima 30000 THAILAND [email protected] Abstract: - A torque control system is an important process in industries. The value of torque which is generated by DC servomotor depends upon a motor current. Since the torque control system uses the estimated current from an observer, it will receive an effect from torque disturbance (load torque) during an operation. The incorrect estimated current from the observer affects a current feedback signal. This paper presents a technique for torque control of DC servomotor by using adaptive load torque compensation. The load torque can be compensated to the observer, the result show that the estimated current error from the observer is reduced. Therefore, this method can be applied to improve an efficiency of the torque control system and estimate the load torque of DC servomotor.

Xu) Abstract Faced with strong demand for robots working in underwater pipeline environment, a novel underwater multi-model locomotion robot is designed and studied in this research. By mimicking the earthworm’s metameric body, the robot is segmented in structure; by synthesizing the earthworm-like peristaltic locomotion mechanism and the propeller-driven swimming mechanism, the robot possesses unique multi-mode locomotion capability. In detail, the in-pipe earthworm- like peristaltic crawling is achieved based on servomotor-driven cords and pre-bent spring-steel belts that work antagonistically, and the three-dimensional underwater swimming is realized by four independently-controlled propellers. With a robot covering made of silicon rubber, the two locomotion modes are tested in underwater environment, through which, the rationality and the effectiveness of the robot design are demonstrated. Aiming at predicting the robotic locomotion performance, mechanical models of the robot are further developed. For the underwater swimming mode, by considering the robot as a spheroid, an equivalent dynamic model is constructed, whose validity is verified via computational fluid dynamics (CFD) simulations; for the in-pipe crawling mode, a classical kinematics model is employed to predict the average locomotion speeds under different gait controls.

  • Servomotor Efficiency by John Mazurkiewicz Baldor Electric
    Servomotor Efficiency By John Mazurkiewicz Baldor Electric In industry we are finding that products must deliver greater performance and reliability while using less electricity. With the cost of electricity steadily increasing, energy efficiency is becoming increasingly relevant. This is also true in motion/position control applications, where servomotors are widely used. You may not be aware that a properly designed servomotor is already highly efficient. It’s how you apply and use the servomotor, which determines whether it is used in an efficient or inefficient manner. Properly designed servomotors Let’s look at what makes a servomotor. First of all, when comparing a servomotor to other motors, which provide the same torque, notice that a servomotor is smaller in diameter. For example, as shown in the photo a 1 horsepower AC induction motor has a 5.6 – 7.6” diameter, an SCR rated motor has a 4.7” OD, a brush–type servomotor is 4” OD, and brushless servomotors is 3.5” sq. The servomotor has intentionally been designed to have a smaller diameter. This is to reduce the rotor inertia, to provide the fast response, which is demanded in motion control applications. Secondly, the servomotor has a feedback device. This added distinguishing feature allows for closed loop control and improved accuracy. Third, in the manufacturing of the servomotor – extra care is taken, and more wire is wound onto the laminations. The space between the teeth of the lamination is stuffed with wire – the slot fill ranges 75 – 80% (most motors are less than 65%). This becomes tough to accomplish in production, however it provides extra torque, and greater efficiency in the servomotor.
