Variable speed drives: all you need to know about speed reducers

A variable speed drive is a device used in electromechanical drives to control the speed and torque of an AC motor by adjusting the motor's input frequency and voltage. Variable speed drives may be either electric, hydraulic, mechanical or even electronic. They control the speed at which a motor operates in a precise and constant manner.

Of course, it would do no harm to use overrated components, so on my milling machine I could use a D8020L (800PIV) for D15, rather than the D4020L (400PIV). The first digit in these component numbers represents their rated voltage (PIV in the case of the diodes). "4" represents 400v and "8" is 800v.

AC Motors vs. DC Motors - What's the Difference? - Thomasnet

3 days agoFor DC motors, the speed of the device is controlled by varying the voltage and current that is applied to the armature coils or windings, or by adjusting the current that flows to the field coils (hence impacting the strength of the magnetic field for the field coil). The speed-current relationship is again a proportional one. Startup Mechanism
