Product Description:
The MAC90B-0-PD-1-B/110-A-C/J1250C/S015 is an AC Servo Motor used for precision motion control applications. This motor is manufactured by Bosch Rexroth Indramat, and provides thermal efficiency, electrical precision, and mechanical balancing to meet the requirements of modern automated systems. This servo motor is rated with a nominal speed of 2000 min⁻¹ to attain a stable and continuous rotation.
The continuous torque for this motor at the standstill is rated at 7.2 Nm, and it increases to 10.5 Nm under thermal overload conditions to provide greater torque density for demanding loading cycles. The continuous current at standstill is 11.9 A, and increases to 17.4 A under high thermal loading so that the motor can support more thermal loading without compromising performance. The MAC90B-0-PD-1-B/110-A-C/J1250C/S015 servo motor has a rotor moment of inertia of 36 × 10⁻⁴ kgm², which provides smooth dynamic behavior and accurate positioning. At 20 °C, this motor has a winding resistance of 0.97 ohms. The winding inductance of this motor is rated at 5.1 mH to provide balanced electrical characteristics for precise control and quick response to input commands. This servo motor can bear a maximum peak pulse current of up to 86 A to deliver high-torque bursts during short-term dynamic loads.
