Product Description:

The MAC071B-0-FS-4-C/095-A-2/AM154SG is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. As a motor for analog drives, it converts drive controller commands into precisely metered mechanical motion for positioning tables, packaging axes, and similar automation tasks that require stable torque and velocity control. This type of servo motor is commonly used where repeatable acceleration, steady low-speed control, and accurate stopping are required during cyclic machine operation. Its integrated layout also helps keep the axis arrangement compact.

A built-in heavy-duty blocking brake lets the shaft stay locked when power is removed, and its holding capacity is rated at 6.5 Nm, which is enough to secure moderate vertical loads without external clamps. The housing aligns against machinery with a 95 mm centering diameter, helping maintain coaxial installation between the motor and the driven element. Heat from the stator is removed through natural convection, so no fan or liquid circuit is required. Under rated electrical excitation, the rotor reaches a nominal speed of 2000 rpm. The motor uses size code 071 and length B, placing it in the mid-torque range of the series. Standard tacho quality supports stable speed feedback behavior when incremental tacho feedback is used by the connected control system.

Position verification is supplied by an integrated absolute encoder, and the feedback arrangement can also support incremental tacho signals for hybrid control loops. Power is routed through a connector on side A, which helps when space behind the motor is limited. Speed feedback voltage is 3 V/1000 rpm, giving the drive a consistent analog reference for closed-loop regulation. Winding code FS identifies the electrical winding set used for this motor and matches it to compatible analog drives. This combination allows the motor to provide both position information and analog speed feedback without requiring a separate external sensing device.
