Product Description

 MAC AC Servo Motors have multiple motor variants, and this section elaborates specifically on the features of MAC071B-0-TS-4-C/095-B-0/WA605XX/S001. MAC is the motor for analogous drives and the variant The nominal motor speed of the MAC series 071B-*-TS is 3000 rpm, where it offers continuous torque at a standstill at 4.4 Nm and increases to 6.6 Nm with a tacho-generator, without holding brake. The continuous current is at a standstill at 7.3 Nm and increases to 11.7 Nm with a tacho-generator, without holding the brake. 

On continuous running operation, AC motors exhaust heat due to windings, and they need to be cooled down to enhance efficiency and reliability. The winding resistance at 20 °C offered by this type of motor is 1.24 ohm and the thermal time constant is 20 mins. The permissible ambient temperature of this equipment range from 0°C to 45 °C. The cooling method for AC motors (synchronous and asynchronous) is air cooling using self-ventilation and forced ventilation cooling. This variant of the MAC machine offers natural convention-type cooling.  

The motor series MAC071B-0-TS-4-C/095-B-0/WA605XX/S001 comes with tacho feedback and mounted incremental or absolute encoder. Tacho feedback enables reporting speed to evaluate the difference in speed from the desired value. On the other hand, absolute encoder feedback enables one to report the exact position without any movement. The motor size is 71, and the length of the motor is type B. The MAC motors can be delivered with or without holding brakes. The tacho type of MAC071B-0-TS-4-C/095-B-0/WA605XX/S001 is standard in this variant of AC servo motor, and it offers operation without blocking the brake.
