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.
