maxon motor is now offering a 300W EC 4-pole industrial motor in addition to its original 200W unit. Both options will deliver high torque at low speeds, quietly and without the need for a gearhead. Despite its 50% increase in power rating, the latest brushless dc model comes in a light, compact package. Its housing is 155 mm long, with a 45 mm square cross section, and the absence of a gearhead means further savings on size, weight and cost.
At 3580 rpm the motor will supply a constant torque of over 670mNm; and its speed-torque gradient of 0.5 rpm/nNm is four times stronger than that of a comparable 2-pole unit.
It enjoys all the benefits of the System maxon ironless winding, whose grooveless stator ensures no detent. The result is excellent control, particularly in positioning tasks. There is also minimal mechanical vibration, so operation is exceptionally smooth and quiet.
Rotor position is signalled through a three-channel encoder, and the unit is fully compatible with maxon’s 4-quadrant DEC 70/10 controller. For the most complex positioning tasks, however, the maxon DES 70/10 servoamplifier is recommended. This combines with the EC 45 4-pole to produce a highly dynamic servodrive with potential for use in industrial automation.
