Product Description:

The MAC090B-0-PD-2-C/130-B-0/SO11 is an AC servo motor from the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. As a motor for analog drives, it converts drive amplifier commands into precise rotary motion for positioning tables, packaging equipment, and similar automated machinery. Its frame size and winding selection place it in the mid-torque range of the series, allowing the motor to work with older control architectures that still rely on analog velocity control. This makes it a practical choice for retrofit applications where dependable motion performance is needed without replacing the surrounding drive system.

The motor uses the PD winding, which sets the copper fill, resistance, and inductance so the motor can reach its rated speed of 1500 rpm on the available bus voltage. Heat generated by the stator is removed through natural convection, so no external blower or liquid circuit is required and installation remains straightforward in enclosed machine spaces. Power enters through a connector on side B, which helps keep cable routing compact when the shaft faces the working area of the machine. Rotor velocity is monitored by an internal tacho generator that outputs 3 V/1000 rpm, giving the drive a linear speed signal for stable analog loop control and overspeed monitoring.

Mechanical alignment relies on a locating pilot of 130 mm in diameter, and this centering surface helps keep coupling runout low when the motor is mounted to an adapter plate or gearbox. The motor has no blocking brake, so any axis that must remain stationary after power is removed needs a separate holding method. The feedback hardware uses tacho feedback, which supports direct speed-loop closure without a digital encoder and keeps the signal chain simple. The tacho has a standard construction grade, making it appropriate for general-purpose motion tasks where normal ripple and linearity tolerance are acceptable.
