Maxon Precision Motors Unveils EC 90 Motors

Maxon Precision Motors Inc. (Burlingame, CA) introduced its new EC 90 Series of brushless pancake motors, which are electronically commutated, thus enabling extremely long motor life since there are no mechanical brushes to wear out. Ball bearings also add to the longevity of the motor. Hall-effect sensors are built into the motor for use as a commutation signal. Due to the low profile and high torque, the motors are suitable for automation and packaging equipment, pick-and-place machines, robotics, and pumps. Control electronics are also available.

The 90mm (3.5in) diameter motor is only 29.1mm (1.1in) in height (not including shaft), yet provides 90W of output power. The maximum continuous torque output is 393mNm (55.6oz-in) while the maximum speed is 5,000rpm. The motor weighs in at 648g (1.4lbs) and the ambient temperature rating is –40°C to +100°C (-40°F to +212°F).
