Product Description:

The MAC090B-0-PD-4-C/110-A-0/WI538LV is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drives, it converts drive-controller commands into precise shaft rotation for indexing tables, packaging machinery, and material-handling axes. The 090 frame size provides medium continuous power in a compact housing suitable for general industrial automation. Integrated speed and position feedback allows the connected controller to correct motion as operating loads change. This feedback supports closed-loop regulation for applications that require repeatable positioning and steady velocity.

A centering diameter of 110 mm keeps the motor concentric with the driven load and helps limit shaft runout. The motor operates at a nominal speed of 1500 rpm, which accommodates common gear ratios used in moderate-speed machinery. Heat leaves the stator through natural convection, so sufficient clearance around the housing is necessary for effective passive cooling. Winding code PD identifies the stator design and its electrical characteristics for compatible 60 V analog amplifiers. The internal tacho generator supplies 3 V/1000 rpm, providing the controller with a linear velocity signal throughout the operating range. Its standard accuracy grade supports consistent speed measurement without requiring a separate external tachometer.

The motor has no holding brake, so an external brake or sustained motor torque is required to secure a vertical load when power is removed. Power conductors exit through a connector on side A, which can shorten cable routing when the drive equipment is positioned on that side of the machine. The feedback assembly uses standard mounting, allowing it to fit the designated motor interface without a special adapter. An incremental encoder delivers position pulses that the controller uses for high-resolution motion control. The tacho signal supplies continuous velocity information, while the encoder pulses allow the controller to track changes in shaft position. These separate feedback channels support accurate speed correction and repeatable indexing during automated operating cycles.
