The combined moulding of the coil, PCB and hall-effect sensors guarantees a reliable, robust construction.
The FaulhaberBX4 high-torque brushless DC servomotor has a modular construction that eliminates complex manufacturing processes and delivers a versatile drive system that is free from adhesives.
The series is completed with a magnetic encoder, an integrated speed controller, a planetary gearhead, as well as external drive electronics.
The four-pole ironless winding and rare earth magnets provide zero cogging and exceptional torque for its size and the combined moulding of the coil, PCB and hall-effect sensors guarantees a reliable, robust construction.
A high torque constant and the shallow slope of the speed torque curve ensures consistent delivery of high torques across a wide speed range and the 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 a differential signal output ensures a stronger signal and maintains integrity, even when using long connecting leadwires.
The option of an integrated speed controller makes this combination user friendly and allows the direct replacement of conventional DC motors but with the additional benefits that electronically commutated motors have to offer.
