文档介绍
h simple profiles.РThe Wound Rotor Induction Motor drive is the traditional choice for mediumРto large belts with repeated starting duty plex profiles that requireР 9Рprecise torque control. The DC motor drive, Variable Fill ic drive,Рand the Variable Mechanical Transmission pete for application onРbelts with extreme profiles or variable speed at running requirements. TheРchoice is dependent on location environment, competitive price, operatingРenergy losses, speed response, and user familiarity. AC Variable FrequencyРdrive and Brush less DC applications are limited to small to medium sizedРbelts that require precise speed control due to higher present costs andРcomplexity. However, with petitive and technical improvements,Рthe use of synthesized waveform electronic drives will expand.Р 10
