Product Description:

The MAC071A-0-ES-3-C/095-B-0/5001 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts commanded current into torque for precise speed and position regulation on assembly lines, packaging stations, and material-handling axes. A standard tachometer embedded in the rear housing supplies a proportional voltage signal, allowing legacy analog controllers to close the velocity loop without digital feedback hardware. This arrangement keeps the control architecture simple while still supporting reliable industrial motion control. The feedback method also suits existing machine platforms that rely on voltage-based speed comparison instead of serial encoder communication.

The motor seats against mounting surfaces through a centering pilot of 95 mm, ensuring concentric alignment with coupled loads. Its frame is designated size 071, and the stator uses winding code ES, a combination that balances thermal dissipation with moderate inertia. With the stack trimmed to motor length A, the unit occupies minimal axial space in multi-axis gantries and other compact machine layouts. The built-in tachometer outputs 1.5 V/1000 rpm, giving the drive a simple way to derive actual speed. At rated current, the rotor reaches 4000 rpm, supporting applications that require elevated conveyor or spindle speeds. This combination supports compact installation while maintaining steady operation through repetitive motion cycles.

Cooling is done by natural convection, eliminating the need for forced-air or liquid cooling hardware. Power is introduced through a connector on side B, keeping cabling clear of the driven machine face and helping maintain orderly cable routing. Speed feedback comes from the internal tachometer, and a second shaft end is provided; this arrangement, described as tachofeedback with a second shaft end, permits external couplings or additional feedback devices to share the shaft. The motor is supplied without a blocking brake, so any static load must be secured by the drive or by an external locking mechanism.
