Danfoss launches Editron EM-PMI375 690-volt electric motor for off-highway and marine applications

Hot on the heels of its new Editron EM-PMI540B electric motor[1] for off-highway machinery and marine vessels, Danfoss Power Solutions[2] has announced the launch of the Editron EM-PMI375 690-volt electric motor. Based on synchronous reluctance-assisted permanent magnet technology, the EM-PMI375 functions as both a motor and a generator. It is designed to work with the Editron EC-C1700B inverter, offering a system solution for 690 V AC and 1,050 V DC applications such as winches, cranes, marine vessels, and mining and material handling machinery.

The Editron EM-PMI375 690 V electric motor is in the same shape and form as the EM-PMI375 500-volt motor, and offers the same robustness, longevity and standardized options. Like its 500-volt counterpart, the EM-PMI375 690 V motor offers up to 96% efficiency throughout its operating range, and Danfoss says it's smaller and lighter than competing products. Developed especially for demanding applications, the motor features a compact and robust aluminum frame structure with an IP67 ingress protection rating.

"Our new EM-PMI375 690 Volt motor and EC-C1700B inverter are the first two pieces of our 690-volt ecosystem, with more to come," said Chao Wang, Head of Portfolio Management for the company's Editron division. "There are few, if any, options out there for true 690-volt mobile-grade inverters and motors. Most are based on industrial solutions, and thus offer much lower vibration and shock tolerance." The EM-PMI375 electric motor is available in four sizes to suit a range of torque and power needs.

Models include: o              T200: continuous torque rating of 200 Nm and power range up to 63 kW o              T500: continuous torque rating of 500 Nm and power range from 66 kW to 158 kW

o              T800: continuous torque rating of 800 Nm and power range from 85 kW to 251 kW o              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 and have low coolant flow requirements.
