MAC021B-0-WS-3-E/032-A-0

The MAC021B-0-WS-3-E/032-A-0 AC Servo Motor from Bosch Rexroth Indramat is a high-performance unit in the MAC AC Servo Motors series designed for demanding industrial automation tasks. This compact motor delivers an exceptionally swift 49 ms acceleration time and a rapid 42 ms deceleration time for precise motion control. With a rated load of 2 HP at an input voltage of 230 V, it provides robust power while maintaining efficiency. The unit features an robust IP65 protection rating, ensuring reliable operation in dusty or wet environments. Its insulation class F permits operation at temperatures up to 155 °C, enhancing durability under high thermal stress.

Equipped with a 32 mm centering diameter for accurate mounting, the MAC021B-0-WS-3-E/032-A-0 operates on a 3-Phase system, delivering stable three-phase power for smooth torque delivery. The motor’s natural convection cooling type offers maintenance-free heat dissipation, while managing continuous operation without auxiliary cooling. It supports up to 0.95 maximum humidity, enabling use in humid conditions. Energy efficiency is further reinforced by its peak regenerated power of 1 kW and continuous regenerated power of 0.2 kW, ensuring energy captured during braking is effectively reused. This unit integrates seamlessly as a Frequency Inverter Drive and connects via the A side power connection for straightforward wiring.

Operationally, this servo motor omits a holding brake to reduce mechanical complexity while relying on integrated electronic braking. It requires careful cable management: encoder shields must be grounded at the NC terminal, separated by at least 100 mm or metallic partitioning from load or mains cables to minimize electromagnetic interference. Power must be disconnected before connector insertion or removal to prevent damage. The motor’s storage temperature range of -20 to +80 °C allows flexible inventory handling, and the compact form factor suits space-constrained installations. Its natural convection cooling and IP65 protection rating enclosure deliver maintenance-free reliability in continuous duty cycles.

Designed for straightforward integration, the MAC021B-0-WS-3-E/032-A-0 supports standard industrial drive systems and pairs naturally with Bosch Rexroth Indramat frequency converters. Its MAC series heritage ensures compatibility with existing control architectures in robotics, CNC machinery, packaging equipment, and general automation platforms. Engineers benefit from the motor’s proven performance, precise positioning, and robust protection in harsh industrial settings. The result is a versatile drive solution that streamlines system design and accelerates time-to-build in high-demand applications.
