Product Description:
The MAC071B-0-PS-3-C/095-B-1/S001 belongs to the MAC AC Servo Motors series manufactured by Bosch Rexroth Indramat. It is a motor for analog drives that supplies closed-loop torque and speed control to indexing tables, packaging axes, and similar automation stations. Because it is intended for analog drive systems, it works with control schemes that regulate motion through commanded current and tacho feedback rather than through integrated digital encoder electronics. A blocking brake is integrated so the shaft can be held at standstill during power-off events, and its centering pilot matches common flange patterns used on mid-frame machines.
The brake can generate holding torque up to 3 Nm, which is suitable for light vertical loads and helps prevent back-driving when power is removed. A centering diameter of 95 mm ensures coaxial alignment between the motor flange and the driven element, which helps reduce radial runout. Heat is released by natural convection, so no external blower is required and the motor layout remains simple. Under rated excitation, the rotor reaches 4000 rpm, supporting direct coupling to high-throughput belt transmissions. Power conductors exit through a connector on side B, keeping cable routing clear of the feedback end and supporting a cleaner installation path in compact machine spaces.
Tacho feedback is supplied on the second shaft end and produces 1.5 V/1000 rpm, giving the analog drive precise velocity information without a digital encoder. Using the tacho on the second shaft end keeps the speed signal separate from the main power connection and supports stable feedback wiring in compact machine layouts. The winding code is PS, which corresponds to the electrical characteristics expected by compatible drives. Mechanical length B places the active stack in the medium range for this motor size, and the frame size is 071. The standard tacho arrangement and internal brake suit moderate inertia loads that require steady speed feedback and secure holding between motion cycles.
