Faulhaber adds to brushless DC servomotor range

An EMS product story
Edited by the Engineeringtalk editorial team Jan 8, 2009

Faulhaber has announced the latest addition to the BX4 series of high torque brushless DC servomotors.

The type 2250 remains only 22mm diameter but offers increased length, peaking at 35W continuous operation.

The modular construction eliminates complex manufacturing processes and delivers a versatile drive system, free from all adhesives.

The series is completed with a magnetic encoder, integrated speed controller, planetary gearhead, as well as external drive electronics.

The four-pole ironless winding together with rare earth magnets result in zero cogging, and the combined moulding of the coil, PCB and hall-effect sensors guarantees a reliable, robust construction.

A high torque constant and shallow slope of the speed torque curve ensures consistent delivery of high torques across a wide speed range, while a choice of rotors provides further flexibility.

The addition of a three-channel magnetic encoder within the same outside diameter provides speed and positional feedback in four factory programmable resolutions of 32, 64, 128 and 256 pulses per revolution.

The option of a line driver with differential signal output ensures a stronger signal and maintains integrity even when using long connecting lead wires.

The option of an integrated speed controller makes this combination suitable for the direct replacement of conventional DC motors but with the additional benefits that electronically commutated motors have to offer.
