The trend is shifting from traditional setups where motor and drive systems are physically separated to more modern arrangements that are streamlined and compact. These newer configurations combine the motor, control, and drive circuitry into a single enclosure, offering more power density.
Traditionally, controllers were positioned separately from motors for various operational benefits, such as minimising exposure to heat, vibration, and harsh environments. Maintaining a safe distance between the motor and vehicle operators was also necessary. However, a new generation of electronics enables drives to be located near or directly on the motor. Another innovation is integrating the drive into the motor’s construction, resulting in a single unit remotely controlled via wired or wireless communications. This integration ensures proximity and facilitates precise matching between the drive and motor.
