Product Description:

The Bosch Rexroth Indramat MAC071b-0-ts-2-f/095-A-0 belongs to the MAC AC Servo Motors series and is supplied as a motor for analog drives used in positioning and speed-controlled axes. Within an automated cell, it converts current or voltage references from legacy controllers into mechanical rotation, allowing precise movement without intermediate gearing when load inertia is compatible. Typical tasks include belt tensioning stations, pick-and-place heads, and small spindle duties where closed-loop velocity information is needed. This arrangement also suits retrofit machinery that still operates with analog motion hardware.

The motor achieves a nominal speed of 3000 min⁻¹, which is the synchronous operating point under rated conditions. At standstill, it can sustain 4.4 Nm while drawing a continuous current of 7.3 A, which helps with thermal sizing in dwell-heavy cycles. Short bursts up to 37 A are permitted for rapid acceleration, and each ampere produces about 0.600 Nm/A, which helps estimate torque in the analog controller. Cooling is done by natural convection, so the normal running phase current of 6.0 A must stay within ambient limits to avoid exceeding the 45-minute thermal time constant.

The flange seats against a 95 mm centering pilot, and power is transferred through a 19 mm k6 shaft sized for standard couplings. Total unit mass is 8.8 kg, and rotor inertia of 9.9 × 10⁻⁴ kg·m² affects acceleration and deceleration response. The motor is sealed to IP65, which protects the winding cavity when the side-A connector is mated to cables no smaller than 0.75 mm². Winding inductance of 10 mH and resistance of 1.24 Ω affect current-loop behavior, while tacho feedback supplies real-time velocity data. The design omits a blocking brake, so position holding must come from drive torque or external mechanics.
