Electro Mechanical Systems (EMS, UK) have announced immediate availability of a new 44mm diameter, rare earth magnet, brushless dc motor from System Faulhaber. The 4490-B is aimed at long life, compact drive applications where size, power-to-weight, power-to-volume and high efficiency are all critical.
Available as a 24V, 36V and 48V motor, the new 4490-B models give the same speed and torque regardless of nominal voltage.
Introduction of the new 4490-B now extends the 4490 family to six models across the size/power range 16mm/11watts to 44mm/201watts. The maximum recommended running speed is 16,000rpm with a torque of up to 190mNm available at 10,000rpm and a stall torque of 2,758 mNm.
