Adjustable Mechanical Variable Speed drive VSD for Washing Machines

Washing machines are used to extract (dewater) solid materials from liquids when they are mixed together in slurry.

A main drive motor supplies power to turn the centrifuge. AC drives are commonly used to power the main drive motor. There are several different types of washing machines, such as: Vertical, horizontal, or scroll (conveyor).

Application?Challenges

Minimize the need for gears or belts to drive the centrifuge. Control and maintain speed during the decanting process Develop high torque at very low speeds. Two motor applications, one for the bowl and one for the scroll. The bowl has a very high-reflected inertia. The scroll is usually in continuous regeneration, as it runs at a slower speed than the bowl and is pulled along. Torque limiting on the scroll is very important. Some configurations require zero-speed operation of the scroll (differential gearbox). Dynamic braking or regenerative modules may be required if the bowl is NOT driven by a drive.

Tips:

A variable-frequency drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.
