2. PRODUCT DESCRIPTION
2.1. Overview
The MGV high-speed motors from Parker are innovating solutions through direct
drive, specifically designed for industrial applications where high speed is needed.
The MGV motors are brushless synchronous servomotors, with permanent magnets,
based on HKW active parts and fully integrated with a water-cooled housing, high
speed ball bearings, encoder …
The water cooling increases the torque density and allows a silent operation.
These motors are taking advantage from the flux weakening principle that allows, at
the same time, a high torque at low speed and a constant power after a given speed.
As there is no current in the rotor, the losses in the rotor are very low
The are two areas :
- A constant torque area from the null speed to the base speed, where the motor
is performing as an axis motor.
- A constant power area that allows to perform at higher speed.
