Danfoss Power Solutions has introduced its new Editron EM-PMI375 690 V electric motor.

Intended for higher-voltage applications, the motor is said to offer ‘market-leading efficiency’ of up to 96%.

Based on synchronous reluctance assisted permanent magnet technology, the EM-PMI375 function as both a motor and a generator.

Designed to work with the Editron EC-C1700B inverter, the motor can deliver 690 V AC or 1050 V DC.

This makes the motor suitable for a series of applications, including winches, cranes, marine vessels and mining and material handling machinery.

The new motor is the same shape and form as the EM-PMI375 500 V model. Developed for demanding industries, the motor uses a robust aluminium frame structure which delivers an ingress protection rating of IP67.

“Our new EM-PMI375 690 V motor and EC-C1700B inverter are the first two pieces of our 690 V ecosystem, with more to come,” said Chao Wang, head of Portfolio Management, Editron division, Danfoss Power Solutions.

“There are few, if any, options out there for true 690 V mobile-grade inverters and motors. Most are based on industrial solutions, and thus offer much lower vibration and shock tolerance. Together, our motors and inverters offer seamless integration into the application.”

The EM-PMI375 690 V has a maximum operational altitude of 3000 metres (the EM-PMI375 500 V has a nominal altitude rating from 1000 to 4000 metres).

EM-PMI375 motor is available in four variants:

T200: Continuous torque rating of 200 Nm and power range up to 63 kW.

T500: Continuous torque rating of 500 Nm and power range from 66 kW to 158 kW.

T800: Continuous torque rating of 800 Nm and power range from 85 kW to 251 kW.

T1100: Continuous torque rating of 1,100 Nm and power range from 177 kW to 296 kW.

All models feature a speed range of up to 4,000 rpm. The motors are liquid cooled, with low coolant flow requirements.
