Product Description:
The MAC025A-0-WS-4-E/040-A-0/WI664LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for use with analog drive controllers, it converts commanded current into controlled shaft motion for positioning and speed-regulated applications. The motor is suitable for pick-and-place equipment, printing machinery, and compact packaging axes that require responsive movement. Its compact housing fits machine layouts where available installation space and cooling airflow are limited.
The WS winding code indicates the stator wiring and resistance profile used with compatible MAC drive amplifiers. Heat is removed through natural convection, so adequate clearance around the housing is required to maintain airflow during continuous operation. The motor has a frame size of 025, providing a compact outside diameter for small automation axes. Its axial length of A uses a short magnetic stack that helps reduce rotor inertia and support rapid indexing cycles. Incoming three-phase power reaches the stator through a locking connector on side A, allowing the cable harness to be routed from that side of the housing. This connector position is useful when the motor is installed against a machine plate that leaves side A accessible.
The motor has no blocking brake, so an external clamp or drive-generated holding torque is required when a load must remain stationary. Position feedback is generated by an incremental encoder with standard mounting, which supplies orthogonal square-wave channels to the connected controller. These signals allow the drive to monitor shaft movement and correct speed or position errors during operation. The feedback configuration also supports tachofeedback with an incremental or absolute encoder, allowing the control system to use the appropriate position and velocity signals without changing the motor’s mechanical interface. The standard encoder mounting keeps the feedback assembly aligned with the shaft while preserving the motor’s compact axial profile.
