Motor Control Solutions for Industrial and Material Handling Equipment

Our name, PE®or Power Electronics® International, Inc.® is synonymous with quality, heavy-duty VFDs and motor control equipment.

<<< Back to all models in this series

Notice for CRH models:

All MMV-CRH™ (Conical Rotor Hoist) models are specialty VFDs – built from the ground up specifically for hoists with a conical-rotor motor and encoder feedback.

Use the drive listed on this page ONLY IF you have this type of application (contact PE® if you are unsure).


For use in hoisting/lifting applications without a mechanical load brake and with a conical-rotor hoist motor (requires an encoder for closed-loop control) up to 40 HP at 575V (45 A max).

Add one of the resistors listed below to your quote request unless one of the exact models shown is already installed in your application.

Important note regarding Encoders and Pulse Count selection: Many conical-rotor motors used in a hoist application have a BUILT-IN (low ppr count) encoder. In this case, you do not need to select an encoder option below (you should also leave the Encoder Pulse Count option as “Standard”).

However, if your motor DOES NOT have an existing encoder, you will need to supply and mount one on the motor. If you will be adding one of the PE® encoder options shown here, make sure you also select the “P2” model option for the MMV-CRH. Contact PE® if you are unsure.

Would you like this product installed in an electrical enclosure or control panel?

No load-brake on your hoist, but don’t have a conical rotor hoist motor? View our MV-U™ models instead.

Does your hoist have a separate mechanical load brake (or a self-locking worm gear)? Use the comparable MX-Ultra™ (Open-Loop) model instead.
