Product Description:

The MAC071B-0-PS-2-C/095-A-0/S047 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it provides closed-loop motion in industrial automation systems that rely on voltage-commanded amplifiers rather than fully digital control. By combining a medium frame size with integrated tachometer feedback, this model delivers precise speed regulation for packaging, material-handling, and indexing axes. Its integrated feedback arrangement supports steady speed correction during load changes and repeatable motion in established analog servo systems.

The motor seats against a machine flange through a centering recess of 95 mm, ensuring concentric alignment between the stator housing and the driven mechanism. Heat produced by the stator is removed through natural convection, so no auxiliary fan or liquid circuit is required when the motor operates within its rated load range. Under nominal conditions, the rotor reaches 4000 rpm, a speed that suits analog velocity loops using ±10 V command signals. The built-in tacho generates 1.5 V/1000 rpm, giving the drive an analog speed signal directly proportional to shaft rotation. Power enters through a sealed electrical connector on side A, which keeps cable routing on the same end as the drive controller and helps simplify panel layout.

The motor has no blocking brake, so holding torque during power-off must come from an external clamp or the mechanical load itself. Velocity feedback is provided by standard tacho feedback, permitting stable analog regulation without a digital encoder. This arrangement suits installations that use analog amplifiers expecting a continuous velocity signal instead of pulse-based encoder data. The active magnetic core uses motor length code B, giving a balanced ratio between torque production and inertia in the 071 frame. Winding code PS identifies the stator wire gauge and turns count, which establish the current constants used by legacy MAC servo amplifiers.
