2 |
Variable frequency driveA method of control by which the motor supply voltage and frequency can be adjusted thereby allowing for controlled acceleration and deceleration of the driven hoist, trolley or bridge.
|
3 |
Variable frequency driveChanges the speed of the motor by changing the voltage and frequency of the electricity supplied to the motor based upon system requirements.

4 |
Variable frequency drivePower control conversion devise for 3 phase motors.
|
5 |
Variable frequency driveA control system that allows the frequency of the current applied to a motor to be varied. The motor is connected to a low-frequency source while standing still; the frequency is then increased gradua [..]
