Product Description:

The MAC090B-0-PD-4-C/110-R-0/WI520LV/S001 is an AC servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for use with analog drives, it receives controlled current from a compatible drive amplifier and converts that electrical input into mechanical rotation for positioning and velocity-control tasks. The motor is suited to industrial automation systems such as NC machining centers, transfer lines, packaging equipment, and material-handling machinery. Its integrated feedback components allow the connected amplifier to monitor rotor movement and correct speed deviations caused by changing loads.

The motor housing relies on natural convection to remove heat, so no external fan or liquid-cooling circuit is required. A centering shoulder of 110 mm aligns the flange with gearboxes or mounting plates and helps limit runout at the mechanical connection. The PD winding establishes electrical characteristics that support operation with compatible Indramat drive amplifiers. At rated excitation, the motor provides a nominal speed of 1500 rpm during continuous operation. The motor has no blocking brake, so an external device must hold the load when power is removed. Ambient air must move freely across the ribbed stator surface to keep the temperature rise within permissible limits at rated current.

Speed regulation is supported by a tachogenerator that delivers 3 V/1000 rpm to the analog control loop. Its calibration grade is standard, making it suitable for general-purpose speed and positioning applications. The feedback path combines the tachometer signal with an incremental encoder, which supplies position pulses for more accurate motion monitoring. Motor phase conductors are routed through a connector on the right side, allowing cables to run along the machine bed without crossing the mounting face. The connector orientation can simplify routing where nearby machine structures restrict cable clearance. Signal and power connections remain physically organized so the drive can process velocity and position information while supplying current to the stator windings.
