Industrial Motors Introduction to TMEIC Motors TMEIC combines the best of Toshiba and Mitsubishi- Electric’s experience in building motors that goes back over 100 years. TMEIC’s motor offering includes induction motors from a few hundred horsepower, up to synchronous motors over 100,000 hp, driving a wide range of industrial applications such as pumps, fans, grinding, conveyors, and compressors. In addition to applications directly connected to utility power, TMEIC motors can be matched with Variable Frequency Drives for ease of starting and for speed control. The VFD allows motor speeds as high as 12,000 rpm. This chart below and pages 4 & 5 illustrate the range of motors available. 100 Synchronous motors are best suited for very high power at lower speeds. Expansion of the oil and gas industry has created 80 Induction motors are best suited for demand for large motors to drive gas compressors and high speed. oil pumps. These motors are located in the production 70 Considerable over lap exists to allow a choice, but the induction motor areas and on interstate pipelines, and are usually usually has the price advantage in the designed with explosion protection. For special 60 overlap area. applications such as driving large compressors and blowers, motor ratings can reach or exceed 100,000 hp. 50 Synchronous Motors Meeting the demand for large motors for the metals Power (MW) 40 industry, TMEIC has produced large synchronous and Induction Motors induction motors for the operation of steel rolling mills. 30 The power levels for these motors go up to about 10 MW. 20 They are covered in a separate brochure. 10 0 0 3000 6000 9000 12000 15000 Rotating Speed (RPM) Features Benefi ts High Reliability resulting from use of proven design Many years of excellent trouble-free service technology, manufacturing expertise, wide use of under difficult working conditions robotics, tight quality control, and testing High Efficiency resulting from detailed analysis of Low electrical losses for high power conversion the electromagnetic field patterns and ventilating air efficiency flows High Strength Insulation applied by robotic Withstand surge and minimizes electrical shorts insulation winding and oversized epoxy resin and winding fatigue failure vacuum impregnation tanks creates strong support and insulation High Mechanical Strength through use of static and Minimizes mechanical deflection and vibration for dynamic strength analysis of stator frame, rotor, shaft longer equipment life and bearings.
