Variable Speed Motor – Inverter Duty, Shaft Grounding, High Surge Protection

The Variable Speed Motor is specifically engineered to deliver optimal efficiency, extended lifespan, and superior reliability in variable speed applications across diverse industrial sectors. Built to endure the demands of inverter-driven operations, this motor incorporates a suite of advanced protective features that ensure dependable and safe performance under fluctuating load and voltage conditions.

A robust 3.5 per unit (PU) surge capability safeguards the motor against voltage transients, while two insulated bearings protect internal components from electrical pitting and stray currents. To further enhance bearing protection and longevity, a shaft grounding device is included to safely dissipate harmful electrical discharge, minimizing wear and extending service life.

Manufactured using Class II shaft materials, the motor offers exceptional mechanical strength, making it ideal for demanding mechanical applications. Its insulation system is based on a Class F temperature rise operating at a 1.0 service factor, ensuring thermal safety and consistent performance during full-load inverter operations.

With a design that supports variable torque and constant torque applications via VFDs, the Variable Speed Motor is a versatile and efficient solution for industries looking to optimize energy use while maintaining operational reliability.
