Product Description:

The Bosch Rexroth Indramat MAC90C-0-KD-1-B/110-A-0/J1250/S01 is an AC servo motor in the MAC AC Servo Motors series. Built for analog drives, it converts control signals into precise rotary motion for packaging stations, transfer units, and other automated assemblies. The motor is supplied without a blocking brake, so an external mechanism or drive-applied torque must hold stationary loads when necessary. Natural convection removes heat without an auxiliary fan. A 110 mm centering pilot aligns the flange with the machine during installation.

Under standstill conditions, the rotor can provide 10.4 Nm of torque while drawing a current of 17.0 A. When acceleration is required, torque rises in proportion to current at a constant of 0.68 Nm/A, allowing predictable control-loop tuning. The shaft reaches a rated speed of 2000 rpm, while the integrated incremental encoder provides position and velocity feedback to the drive. The motor has a thermal time constant of 60 min, allowing its temperature to rise gradually during cyclic operation. Mechanical power is transferred through a shaft with a diameter of 24 mm. The power plug is oriented on side A, which supports convenient cable routing when the motor is installed in an automated machine.

The housing has an ingress protection rating of IP65, preventing dust ingress and guarding against low-pressure water jets. Short bursts of demand are supported by a peak pulse current of 125 A, providing additional torque for rapid acceleration. The electromagnetic circuit has a winding inductance of 3.6 mH and a winding resistance of 0.60 Ω. These electrical values help a compatible analog amplifier regulate current through the motor windings. Proper drive settings are necessary to manage the available pulse current while keeping the motor within its thermal limits. The sealed housing also allows operation near machinery where dust or occasional water spray may be present.
