Gear drive specialist, Bauer Gear Motor’s new range of permanent magnet synchronous motors (PMSM) is said to deliver high levels of energy saving and reduced costs for industry. The motors fulfil the requirements of the soon-to-be-implemented IE4 classification and have the potential to achieve energy savings of up to 40 per cent compared with an IE2 inverter- driven squirrel cage motor.
The PMSM series is an environmentally friendly range, employing an efficient design of rotor which offers a number of key benefits. It reduces heat losses from the rotor by 100 per cent, total losses by approximately 25 per cent, and increases total efficiency by 10 per cent or more. This improved performance translates into lower total cost of ownership, a reduction in CO2 emissions, and ongoing savings that buffer against increasing energy costs.
PMSM synchronous motors offer improved efficiency when compared with induction motors even under partial load conditions; and high efficiency under rated operating conditions. They have higher power density, which, for geared motors, yields higher system efficiency with minimal installation volume – and also reduced weight. PMSM drives can produce higher torques for the same installation volume as conventional induction motors.
