maxon motor’s newly designed 70 Watts flat brushless motor delivers a max. continuous torque of 130 mNm at an efficiency of up to 85%. The new motor in its 45 mm diameter is available with Hall sensors and comes in four windings (24, 30, 36, 48 V). It can be combined with more than 54 different planetary and spur gearheads. For motion control purposes, maxon provides a wide variety of servo controllers and positioning controllers to select from.

Portescap has expanded its family of brush DC motors by introducing 35GLT motors. These RoHS-compliant motors have a 35mm housing and weigh just 360 grams, while delivering a 40% increase in torque-to-volume ratio when compared with standard iron core motors of similar frame size. The maximum continuous torque approaches 150 mNm in the 35GLT, a 25% improvement over similar conventional models. They are available with five winding types in the voltage range of 24V to 90V, and are cost-effectively customizable for use with a range of gearboxes and encoders.

PITTMAN Series GM8000 brush-commutated DC gearmotors from Servo2Go.com feature 11-slot skewed armatures to minimize magnetic cogging (or reluctance torque) and promote quiet and smooth operation.

Series GM8000 gearmotors are available with a range of 11 standard reduction ratios from 6.3:1 to 187.7:1. Peak torques up to 175 oz-in can be achieved with wide-face gear options. Armatures are skewed to minimize magnetic cogging, even at low speeds, and windings are resin-impregnated for greater reliability in incremental motion applications. Two-pole permanent magnet stators are constructed of ceramic magnets enclosed in heavy-gauge steel return rings. Diamond-turned commutators ensure maximum brush life.
