Product Description:

The MAC071C-0-NS-3-C/095-A-1 is an AC servo motor produced by Bosch Rexroth Indramat and assigned to the MAC AC Servo Motors series. Designed for analog drives in automated machinery, it converts controlled electrical input into precise rotary motion for positioning, contouring, and cyclic tasks in packaging, printing, and handling systems. Its mechanical layout, electrical connections, and built-in feedback arrangement support integration with legacy drive amplifiers that rely on tachogenerator signals for closed-loop speed control.

The housing uses a 95 mm centering diameter, which helps align the motor accurately with gearboxes or machine mounting plates. The electromagnetic package uses winding code NS, which corresponds to the stator resistance and inductance used for torque production at moderate current. Under rated conditions, the shaft reaches a 3000 rpm nominal speed, making it suitable for common industrial motion profiles. Cooling is provided by natural convection, so the motor should be installed where surrounding air can carry heat away from the housing. For holding during power-off states, the brake provides 3 Nm locking torque to help prevent axis drift.

Electrical power enters through a connector on side A, which can simplify cable routing when the flange faces the machine drive train. The motor is supplied with tacho feedback and a second shaft end, allowing analog velocity control without the need for an external encoder arrangement. The tachogenerator output is 3 V per 1000 rpm, providing a linear speed-related signal to the controller during operation. The dimensional designation of motor size 071 with length code C places this unit in the mid-range of the series, giving a practical balance between torque capability and installation depth. The tacho quality is standard.
