Product Description:

The MAC025B-0-ZS-4-E/040-B-1/WI651LV/S001 is a servo motor from Bosch Rexroth Indramat that belongs to the MAC AC Servo Motors series. Intended for analog drive controllers, the unit converts ±10 V velocity or torque commands into controlled mechanical rotation for indexing tables, loaders, and general handling equipment. It also carries integrated Hall sensors and commutation tracks, letting legacy MAC amplifiers recognize rotor position without additional tuning during startup. That signal arrangement supports stable commutation on older servo systems that still rely on analog command architecture.

The three-phase supply leads terminate at a connector on side B, keeping encoder and brake wiring clear of the opposite face and easing cable routing in compact machine layouts. The motor is cooled by natural convection, so no external fan or liquid circuit is required, and the housing fins dissipate heat during continuous duty. A standard blocking brake secures vertical loads whenever the drive disables torque. Because it is a motor for analog drives, the internal windings are matched to legacy servo amplifiers that issue analog reference signals.

The feedback stage uses tachometer feedback with an incremental or absolute encoder, allowing the controller to work with either velocity-based tachometer signals or high-resolution position data. The primary sensor is an incremental encoder with standard mounting, which uses a common mechanical interface for many MAC bracket kits. Mechanical dimensions follow frame rating B with a stack length code of 025, giving the motor a compact envelope for low-torque axes. The dual feedback arrangement supports applications that need either straightforward speed feedback or more detailed position information from the same motor platform. That compact size helps the motor fit smaller axis spaces where larger frames would require more installation clearance.
