maxon motor brushless DC flat motors with integrated encoder

Brushless flat motors from maxon motor feature pancake form factor and torque ratings. The product’s integrated mile encoder maintains the motor’s low profile and includes high-resolution encoder feedback.

The encoder operates by measuring the fields generated by eddy currents in a target disc. This is claimed to offer improvements over traditional encoder technology in the form of environmental robustness, improved speed capabilities and an increase tolerance against external interference. The integrated encoder, when used with a matching motor position control unit, will control the unit to resolutions of up to 25,600 qc/rev.

There are three power levels - 30, 50 and 70 W - in a 45 mm diameter, and also a high-torque 90 W version in a 90 mm diameter. The 45 mm version is available with both PCB-mounted connectors or a smaller footprint cable version. The product is suitable for driving loads directly with high degrees of speed and position control in robotics and factory automation applications.
