Fall River, MA -- The new Maxon "EC-max 40-mm" brushless motors deliver the performance and lifetime of a brushless motor, but at a reduced cost due to improved automated manufacturing processes. 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 40 mm (1.57 in) while the length is 88 mm (3.46 in). Continuous output power is 120 watts, while maximum speed is 12,000 RPM. Maximum continuous torque is up to 195 mNm (27.6 oz-in) depending on the winding. Ambient temperature range is -40° to 100° C (-40° to 212° F). Utilizing high-energy neodymium magnets results in a very responsive mechanical time constant of 5 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.
