Product Description:

The MAC090B-0-JD-4C/110-A is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Designed for analog drive systems, this unit turns drive-controller output into precise shaft rotation that can be integrated into indexing tables, pick-and-place axes, or packaging stations on automated production lines. The motor uses natural convection for cooling and maintains full performance at mounting elevations up to 1000 m.

Mechanical alignment is aided by a centering diameter of 110 mm, allowing the frame to seat accurately against standard machine flanges. The enclosure carries an IP65 rating, which seals out dust and low-pressure water jets so the motor can be mounted near process zones without an additional housing. Under rated operating conditions, the shaft reaches a nominal speed of 3000 rpm, while a standstill torque of 6.7 Nm helps the axis resist load when motion is paused. For dynamic events, the drive can command a peak pulse current of 137 A, and continuous holding current is limited to 18.2 A to balance thermal rise with magnetic force. Encoder or tacho feedback options supply incremental or absolute position data back to the analog controller, helping velocity loops respond quickly and accurately.

Electrical constants show how the winding converts amperes into torque. Each ampere produces 0.41 Nm/A, so drive tuning tables can estimate acceleration with simple scaling. The motor’s inductance of 2.0 mH filters high-frequency current ripple, while a phase resistance of 0.38 Ohm sets copper loss at steady load. With a 60-minute thermal time constant, the stator temperature rises gradually and allows short overload periods without exceeding insulation limits. Side-A power entry and the standard tacho output support the electrical characteristics used for motor matching and stable drive operation.
