Product Description:
The MAC025B-0-ZS-3-E/040-B-0 is an AC servo motor produced by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. The unit is intended for position and velocity control in automated machinery that relies on analog drive amplifiers, so it forms the electromechanical link between the controller and the mechanical load. This operating concept suits machines that still use analog command structures and require motor-mounted feedback for stable axis response. Its rotor, stator, and feedback elements are optimized for responsive motion control, making the motor appropriate for packaging stations, light handling axes, and other applications that call for continuous duty cycles without forced cooling.
The motor is supplied without a blocking brake, which means external holding devices or drive torque must maintain position when power is removed. Heat is dissipated through natural convection; no fan or liquid circuit is integrated, so mounting orientation should permit free airflow around the housing. This cooling arrangement keeps the assembly simple and avoids the added space required by blowers or liquid hoses. The motor includes tacho feedback and a second shaft end, allowing velocity sensing and mechanical mounting of an additional encoder or pulley. The motor has a length code of 025, which indicates the active stack height, and a frame size of B, which sets the flange pattern and winding envelope.
Cabling is routed through a connector on side B, simplifying installation in cabinets where the drive cable must exit opposite the load side. As a motor for analog drives, it interfaces directly with voltage-controlled amplifiers that regulate armature current by monitoring tacho voltage rather than digital encoder data. This arrangement supports operation with existing analog servo controllers while preserving responsive motion control for legacy automation systems. It also suits retrofit applications where the amplifier topology is already established and digital feedback hardware is not being added.
