Product Description

The Rexroth Bosch is a company that is known for developing the hardware that is required for various products that range from drive controllers to drive converters. This group also creates brushless servo AC motors that are used in fabricating semiconductors, machine tools, axes, packing equipment, etc. We are Wake Industrial a distributor that sells both, the Bosch Rexroth and Indramat products. One of their motors is the MAC071C-0-GS-4-C/095-B-2/WA612XX/S001.

This motor belongs to the MAC series. The motor size is 071 and the length is “C”. The nominal motor speed for these motors is 6000min-1. The continuous torque at a standstill is 6.6 (9.9) 5) Nm. The mass of this motor is 11 kg. The continuous current at a standstill is 22.0 (35.4) 5) A. The rotor moment of inertia is 12.9 x 10-4 kgm2. The motor's excellent torque-inertia ratio results in high dynamic performance. Effective heat dissipation enables a high overload capacity, and the motor can utilize peak torque across a wide speed range. Its high power-to-weight ratio is attributed to its compact construction. Continuous start-stop operations with high repetition rates are made possible by electronic commutation, and the stator's special design and high-resolution tacho feedback contribute to excellent smooth running qualities. The brushless motor design, along with lifetime lubricated bearings, allows direct use in tough conditions, such as those exposed to coolants and oils, due to the motor's IP65-rated enclosure and protected power, tacho feedback, and encoder cables. The motor windings and housing are equipped with integrated thermo switches to protect against overload damage by monitoring motor temperature.

This motor uses a natural convection method for cooling down. Natural convection means the heat from the object is transferred away by the air in the process of natural cooling, without the use of fans or blowers.
