Product Description:

The MAC025B-0-ZS-4-E/040-B-0/WI651LV belongs to the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. It is a compact AC servo motor intended for analog drive systems where precise velocity and torque control are required. By combining electrical commutation with integrated position feedback, the unit serves as an actuator for tasks such as indexing tables, light pick-and-place axes, or auxiliary spindles in automated machinery. This type of motor is suited to compact motion axes that rely on stable response from an external analog controller.

This motor uses size code 025 and frame size B, giving it a consistent mechanical envelope when aligning multiple axes. Heat generated in the stator is removed through natural convection, eliminating the need for external blowers or liquid circuits in low to moderate duty cycles. Electrical power is introduced through a power connector on side B, which can simplify cable routing where space behind the motor face is limited. For speed and position regulation, the motor can use tacho feedback, an incremental encoder, or an absolute encoder, allowing the drive to match loop requirements from coarse velocity trimming to fine positioning. This gives the control loop flexibility without changing the basic motor housing.

The motor is supplied without a blocking brake, so holding torque must be provided electrically or through external mechanics when the axis is idle. Where a load must remain fixed at standstill, a mechanical clamp or drive-generated torque is required. Applications that depend on higher-resolution edge counting can use an incremental encoder with standard mounting, which remains compatible with conventional analog velocity controllers. Standard mounting also helps the feedback device fit common interface hardware used on older motion systems.
