Hot on the heels of its new Ediron EM-PMI540B electric motor for off-highway and marine applications, Danfoss Power Solutions has announced the launch of the Ediron EM-PMI375 690-volt electric motor.
Based on reluctance-assisted permanent magnet technology, the EM-PMI375 works as both a motor and a generator. Designed to work with the Ediron EC-C1700B inverter, it provides a system solution for 690 V AC and 1,050 V DC applications such as winches, cranes, marine vessels, and mining and material handling equipment.
The Ediron EM-PMI375 690 V electric motor is in the same form factor as the EM-PMI375 500-volt motor, and offers the same durability, longevity and standard 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 is smaller and lighter than competing products. Developed especially for demanding applications, the motor features a robust aluminum frame with an IP67 ingress protection rating.
“Our new EM-PMI375 690 Volt motor and EC-C1700B are the first two pieces of our 690-volt ecosystem, with more to come,” said Chao Wang, Head of Portfolio Management at the company's Ediron division. “There are few, if any, options available for true 690-volt inverters and motors. Most are based on industrial solutions, and therefore offer low vibration and shock tolerance. “
The EM-PMI375 stepper motor is available in four sizes to suit a range of torque and power requirements. Models include:
• T200: 200 Nm torque and up to 63 kW power
• T500: continuous torque of 500 Nm and power from 66 kW to 158 kW
• T800: continuous torque of 800 Nm and power from 85 kW to 251 kW
• T1100: continuous torque of 1,100 Nm and power from 177 kW to 296 kW
All models have a speed range of up to 4,000 rpm. The motors are liquid cooled and have low cooling flow requirements.
