Fall River, MA -- The new Maxon "EC-powermax 30-mm" brushless motors deliver the performance and lifetime of a brushless motor, but in a very compact package. The motors are electronically commutated, thus enabling extremely long motor life, since there are simply no mechanical brushes to wear out. Hall effect sensors are built in to the motor in order to provide feedback to the control electronics. By assembling the motor such that the coils are outside the rotor, good heat dissipation and high overload capability is attained.

The motor has a stainless steel housing and a diameter of 30 mm (1.2 in) while the length is 64 mm (2.5 in), and weighs in at 270 g (9.5 oz). Continuous output power is 200 watts, and maximum speed is 22,000 RPM. Using a 4-pole rotor allows for an impressive maximum continuous torque of 130 mNm (18.4 oz-in). Ambient temperature range is -40O to 100O C (-40O to 212O F). Utilizing high-energy neodymium magnets results in an extremely responsive mechanical time constant of <2 ms, while minimizing overall size. Using electronic commutation allows for minimum electrical noise. Motors are offered with several different windings to optimize desired speed with available voltage. Complementing the motors are gearheads, encoders, brakes, and control electronics.
