MAC025B-0-ZS-2-E/040-B-1/S001
MAC AC Servo Motors
The MAC025B-0-ZS-2-E/040-B-1/S001, Bosch Rexroth Indramat, MAC AC Servo Motors servomotor is engineered for industrial drive systems requiring high precision and compact form factor. It features a laminated rotor core with permanent magnets and complies with a Size Code of 25 for seamless integration into standardized mounting interfaces. The motor’s Output Shaft Position on Side A and a DIN 6885–compliant Output Shaft Type keyway ensure rigid torque transmission and alignment. Designed for use exclusively with Bosch Rexroth drive amplifiers, this unit always incorporates a high-resolution tacho feedback for accurate speed monitoring.
Boasting a Product Group classification within the MAC series, this servomotor adopts a Windings Type of ZS to optimize torque ripple and thermal performance. Its Cooling Mode of Natural Convection eliminates moving parts and reduces maintenance, while the prime Housing Coat Color of Black provides corrosion resistance in harsh environments. The Mounting Mode specified as Design B05 with a 40 mm pilot flange diameter streamlines mechanical assembly. A Second Shaft End of No underscores the design’s focus on single-shaft output for simplified cable routing and safety compliance.
Installation and maintenance benefit from the motor’s closed-circuit blocking brake design, which secures loads during power interruptions, and a mandatory pre-commissioning grind-in procedure when units have been in storage beyond two years. Dust-resistant seals safeguard internal windings, and the motor’s horizontal orientation requirement prevents liquid ingress around the shaft, ensuring durability. Grounding to the associated drive amplifier is critical for EMC compliance and sustained reliability under continuous industrial operation.
