The Bosch Rexroth Indramat MAC090B-0-PD-1-B/110-A-1/-DI00625 AC servo motor from the MAC AC Servo Motors series delivers high-speed response and precise control for demanding industrial applications. Engineered to comply with the DIN 40 050 standard for mechanical construction, this MAC Permanent Magnet Motor integrates a natural convection cooling system and a standard electromagnetic blocking brake for fail-safe operation. The housing design provides robust protection against dust and moisture ingress, while contact guards shield internal components from external hazards. An incremental encoder with shock-damped mounting affords accurate position feedback, making the motor suitable for servo loops requiring high dynamic performance.
Technical specifications are extensive: the motor develops a continuous torque at standstill of 7.2 Nm with a continuous current at standstill of 11.9 A, and accommodates a maximum peak of pulse current of 86 A for short-term overloads. It produces motion at a nominal motor speed of 2000 RPM and features a torque constant at 20 °C of 0.68 Nm/A. The rotor’s dynamic characteristics include a rotor moment of inertia of 53 × 10^-4 kg·m² and a thermal time constant of 60 min. Winding parameters are defined by a windings inductance of 3.6 mH and a windings resistance at 20 °C of 0.60 Ω. The motor’s mass of 18 Kg supports stable installation on various machine frames. Additional construction details include a motor size of 90, motor length code B, and an IP65 rated output shaft sealing.
Operational performance is optimized through natural convection cooling, classified as Cooling Type: Natural Convection, with differential IP ratings: main power supply terminals IP65, cooling section IP24, and blower motor IP44. The integrated thermoswitches prevent overheating by monitoring winding temperature and triggering controlled shutdowns under overload conditions. Reliable performance is maintained when operating within ambient temperatures of 0 to 45 °C and at elevations up to 1000 m above sea level; deviations necessitate a load-factor adjustment. The built-in electromagnetic blocking brake sustains shaft position during power interruptions, and the incremental encoder supplies high-resolution feedback without auxiliary power.
System integration is facilitated through seamless compatibility with Bosch Rexroth Indramat DSC drive controllers, supporting advanced motion functions such as synchronous multi-axis coordination and programmable acceleration profiles. The motor’s standard blocking brake and encoder interface are compatible with industry-standard drive inputs, minimizing cabling complexity. Target applications include printing presses, packaging machinery, industrial robots, textile equipment, transfer systems, and CNC machine tools where precision, repeatability, and dynamic response are critical. The MAC090B-0-PD-1-B/110-A-1/-DI00625 offers a balanced combination of torque density, thermal stability, and ingress protection for robust industrial automation deployments.
