EC Motor for Demanding Tasks
High energy prices make good efficiency an important characteristic of modern motors. The motor and fan specialist ebm-papst addresses this fact with its new EC motor BG 43. Developed for everyday use, the robust drive scores with an efficiency of more than 80%. The motor is suitable for practically all fields of conventional and sophisticated technology, from radial-flow fans for cold/hot air door curtains and air-conditioning systems to pump drives in medical technology to industrial systems engineering, if required also in conjunction with a gearbox. There are even solutions for installation when there is a lack of space.
The three core motor is available in three sizes, with 75, 150 and 300 W output and in protection rating IP20 (IP54 available on request). Both clockwise and anticlockwise rotation versions are available. Precision ball bearings reduce operating noise and allow very long, maintenance-free operating times. Depending on the local situation, the high-performance commutation and control electronics can also be installed offset from the actual motor housing, a not inconsiderable advantage, for example in air shafts or compact systems engineering. The 8-pin rotor with neodymium solenoids, in conjunction with sensorless sine commutation, allows very good speed control.
