Product Description:

The MAC090C-2-GD4-C/110-A-0/WI520LX/S001 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is used with analog drives in systems where a voltage reference controls speed or torque, making it suitable for retrofitting CNC machines and assembly lines that rely on ±10 V control signals. By converting those commands into controlled rotary power, the unit positions tooling, conveyors, or actuators with repeatable accuracy in automated equipment.

The motor operates at a nominal speed of 3000 rpm, enabling coordinated motion with standard controllers. At standstill, it supplies 16.0 Nm of torque while drawing 41.3 A, and during rapid acceleration the phase current can rise to 196 A. A torque constant of 0.43 Nm/A provides a direct relationship between current and output torque. Axial surface cooling moves blower airflow across the stator, and the motor is supplied without a blocking brake, so static holding must be provided by the machine. The power connector is located on side A, and the motor uses an internal tachogenerator for speed feedback in analog drive operation.

The separate blower operates on AC 115 V, so cooling airflow remains available even when shaft speed is low. A sealed housing rated IP65 protects the internal windings from dust and water jets in industrial environments. The GD winding code corresponds to a winding inductance of 1.5 mH and a phase resistance of 0.24 Ω, which influence the motor’s electrical response. The motor has a thermal time constant of 45 min, allowing overloads for limited periods before stator temperature rises significantly. The tachogenerator provides 3 V per 1000 rpm for speed feedback, and a 110 mm pilot diameter helps center the flange accurately against gearboxes or mounting plates.
