Danfoss Power Solutions has introduced its Editron EM-PMI540B electric motor for electric or hybrid drivetrains in demanding applications such as off-highway machinery and marine vessels.
Based on synchronous reluctance-assisted permanent magnet technology, the EM-PMI540B functions as both a motor and a generator. It offers efficiency of approximately 96% and non-stop continuous power for as long as the duty cycle requires. A high operational altitude of up to 4,000 meters enables expanded use in mining and forestry applications.
The EM-PMI540B is small and light, enabling straightforward machine integration. Its housing has an ingress protection rating of IP67.
The EM-PMI540B has more mounting and shaft options than its predecessor, the EM-PMI540A—such as a flange mount, various foot mountings, through-shaft, and spline—common housing and end shield designs across each size, and modest improvements in motor diameter.
The EM-PMI540B electric motor is available in four sizes to suit a range of torque and power needs—the T1500, T2000, T3000 and T4000 correspond to continuous torque ratings of 1,500 Nm up to 4,000 Nm. The full line of motors has power ranges starting at 119 kW and topping out at 1,000 kW and speed ranges from 0 to 4,000 rpm. The motor is liquid-cooled and features low coolant flow requirements with an allowed coolant temperature of up to 65° C.
“Our new Editron EM-PMI540B electric motor builds on the popularity and market-leading performance of our PMI540A. To our high efficiency ratings and 24/7 continuous power, we’ve added universal mounting options and a higher altitude rating to meet market demands. These combined features are especially beneficial in mining, harbor material handling, and forestry machinery,” said Fredrik Wigh, Senior Product Manager, Electric Machines at Danfoss Power Solutions. “But the motors’ high efficiency and smaller size makes them ideal for many other electric and hybrid machines, particularly those operating in demanding, rough environments.”
