Product Description

Rexroth, Indramat designs and develops highly operational industrial motor drives. The company is well known for developing highly reliable industrial drives. Wake Industrial is a top seller of the products of the highly dependable industrial parts. MAC AC Servo Motors series is one of its industrial drive products. It is permanently excited motors which work on the electronic commutation principle.

The given servo motors typically employ a tachofeedback, however, another encoder can be mounted for the position evaluation. The additional encoder can be incremental encoder or an absolute encoder. The operating reliability is high due to the structural design of the motor. Its operation is typically maintenance-free partly because of brushless design and lifelong lubricated bearings. Moreover, the motors can be employed in places with extremely machine unfriendly environment as the design of the motor is as per the International Protection IP-65. The temperature controlling is supervised with thermal switches connected to the windings and stator housing which prevents damages from overheating. The output of the motor is dynamically high due to favorable torque-inertia ratio, high overload capacity, compact design and excellent smooth running qualities.

The nominal speed of the motor is 3000 rpm for the part number MAC090A-0-RD-4-C/110-A-0/WA610XX. The cooling in this part is through natural convection. The feedback on the motor is tachofeedback with mounted incremental or absolute encoder. The power connection is to the side A of the motor drive. This part is without holding brake. The continuous torque at standstill is 3.5 Nm with the continuous current at standstill is 11.4 A. The rotor moment of inertia is 0.002 Kilogram Square Meter. The torque constant is 0.34 Nm/A. The winding resistance is 0.56 Ohms.
