MAC090B-0-ND-4-C/110-A-0/WA610XX

The Bosch Rexroth Indramat MAC090B-0-ND-4-C/110-A-0/WA610XX servo motor from the MAC AC Servo Motors series by Bosch Rexroth Indramat delivers a compact three-phase synchronous design optimized for high-precision automation tasks. It features a Motor Size 90 and Motor Length B configuration with a Nominal voltage (axial cooling) AC 230 or 115 V rating, ensuring compatibility with a wide range of industrial drive systems. The unit incorporates Natural Convection cooling, eliminating the need for auxiliary fans, and includes a B encoder feedback assembly with Voltage constant (tachogenerator) 0.0286 V/min-1 for precise speed regulation. The power connector on Side A simplifies installation, while the Not Equipped blocking brake variant reduces maintenance complexity. Designed for variable-speed applications, this motor type supports up to Frequency (radial cooling) 50/60 Hz input and integrates seamlessly into NC machine tools and automated manufacturing lines.

Performance characteristics of this MAC permanent magnet motor prioritize rapid response and sustained torque under load. It delivers a Continuous current at standstill 13.0 (20.0) A and a Continuous torque at standstill 6.7 (10.5) Nm rating for steady-state operations, complemented by a Pulse current (peak) 98 A capability for high dynamic acceleration. The heavy-duty Holding torque 14 Nm and a Release delay (heavy-duty) 70 ms ensure reliable load retention when power is removed. The motor’s Moment of inertia (standard) 1.06 x 10-4 kgm2 contributes to its excellent acceleration characteristics in position control loops. It withstands ambient fluctuations with a Permissible storage and transport temperature -20 to +80°C range, making it suitable for global deployment. This combination of electrical and mechanical parameters supports precise torque control, rapid acceleration, and smooth deceleration in demanding CNC, woodworking, and assembly applications.

Engineered for long-term reliability, the MAC090B-0-ND-4-C/110-A-0/WA610XX benefits from a robust permanent magnet rotor and precision bearings, minimizing wear in continuous-duty cycles. Its incremental or absolute encoder feedback (4-C configuration) ensures accurate position evaluation, while the natural convection cooling path reduces contamination risk and maintenance intervals. The motor type ND winding is optimized for 3000 rpm industrial use, delivering consistent performance in high-speed indexing and contouring tasks. Integration with compatible servo drives is streamlined through standardized mounting dimensions and clear diagnostic indicators on the front panel. Ideal for automated assembly, automotive production machines, and high-precision machining centers, this servo motor aligns with rigorous industrial standards for accuracy and uptime.
