Compact Design

Enhanced cooling efficiency enables these motors to be smaller and lighter, reducing the need for large heat sinks and extensive ventilation systems.

 

Ingress Protection

Thermal Protection

Embedded 100 Ω platinum stator RTDs, two per phase terminated in an auxiliary box, help protect the motor’s insulation system from excessive heat and unsafe operation.

 

Humidity Protection

120V space heater is included in all frames.

 

Vibration Provisions

Designed for mounting vibration sensors (1/4” NPT) on each bearing bracket.

 

Drive Duty Compatibility 

The insulation meets NEMA MG1 Part 31 standards.  It can be paired with a UL-Listed Medium Voltage Drive, which features a motor-friendly multiphase neutral point clamped output.

 

Rotor Options:

Aluminum Rotor

High-pressure diecast aluminum rotors offer a lightweight, cost-effective solution. Low rotor inertia improves acceleration and deceleration, while excellent thermal conductivity enhances cooling. Corrosion-resistant properties increase reliability in harsh environments.

 

Copper Bar Rotor

Copper bar rotors deliver high electrical conductivity for improved efficiency and reduced losses. They provide higher starting torque and operate at lower temperatures, making them ideal for heavy-duty, high-performance applications where thermal stability and energy efficiency are critical.
