Product Description:

The MAC021A-0-YS-3-E/032-B-0/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. As an electromechanical actuator, it transforms drive controller output into controlled rotary motion for tasks such as indexing, follow-up positioning, or light material handling on automated lines. When coupled with compatible Indramat drive amplifiers, this motor supplies rapid torque rise and precise speed feedback, supporting tight process tolerances in compact machinery. Its compact format also suits installations where multiple axes must fit into a limited machine envelope without sacrificing closed-loop motion control.

Thermal management is handled by natural convection, so the housing fins must remain unobstructed for passive heat release and no auxiliary fan is required. Speed regulation accuracy is maintained with tacho feedback, a built-in DC tacho generator that relays actual shaft velocity back to the drive. Because the feedback device is integrated into the motor, the amplifier can compare commanded and actual speed without separate external sensing hardware. The power interface is a connector mounted on side B, allowing cables to exit away from the driven load and simplifying panel layout. With the slender 021 frame size, the rotor inertia remains low, enabling fast acceleration of light tooling. The design includes no blocking brake, so any axis that needs static holding torque must rely on an external brake or closed-loop drive torque.

The motor has motor length A, giving it a short axial footprint suited to closely spaced multi-axis setups. A second shaft end is provided, permitting direct attachment of an additional encoder, handwheel, or mechanical fan without affecting the primary coupling. That arrangement allows auxiliary devices to be driven from the motor without changing the main shaft connection at the load. The unit is a motor for analog drives, meaning it expects ±10 V command signals and analog tacho feedback loops typical of legacy Indramat controllers. Older control systems can use it where digital interfaces are not available.
