Permanent Magnetic Motor (PMM) Driveheads
Description
The M-75 PMM is designed for medium to high horsepower applications, while the M-105 PMM is designed for high horsepower applications. Our dedication to safety is front and center in the PMM with an integrated failsafe resistive brake, a single rotating external part and no overhung motor mass for a safe install. The PMM drive is a friend to the environment as it requires less energy to operate and is extremely quiet.
Features/Benefits
- Safety provided by:
- Integrated failsafe electronic resistive brake
- Elimination of rotating parts, such as belts and sheaves
- Perfectly balance lifting with no overhung motor mass
- Highly efficient motor that reduces electrical energy consumption and greenhouse gas emissions
- Delivers exceptionally high starting torque and rated torque efficiently over entire operating RPM
- Quiet operation – 68 dB at 10′ (3 m)
- Provides a fully optimized system when paired with the Guardian II VFD
