Variable Speed Air Cooled Drives Adjustable Speed Drives

11/10/2010 · When an induction motor is connected to a full voltage supply, it draws several times (up to about 6 times) its rated current. As the load accelerates, the available torque usually drops a little and then rises to a peak while the current remains very high until the motor approaches full speed.

The Variable Speed Drive operates from the 480V single phase supply connected to L1 and L2. The ZENER VSD takes the single phase AC Supply and converts it to a 3 Phase output suitable for a standard 3 phase 415V motor. The ZENER Drive actually does more than just convert from a single to 3 phase supply. The VSD controls the output waveform to allow the speed to be controlled by …

controlling motor speed. Variable Speed Drive (VSD) frequency, the motor does not require a high level of current. The VFD incrementally increases the frequency and motor speed until the desired speed is met. The current level of the motor never exceeds the full load amp rating of the motor at any time during its start or operation. In addition to the benefit of low starting current, motor
