Product Description:

The MAC090B-0-JD-1-B/110-A-0-101250 is a servo motor manufactured by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed for analog drives, it converts controlled current into rotational motion for positioning and speed-regulated automation axes. It is suited for conveyors, pick-and-place devices, and machine tool spindles where analog command interfaces remain in service. Integrated feedback allows the connected amplifier to monitor motion and correct axis response during operation. This arrangement supports accurate movement in industrial systems that still use established analog control architecture.

At a nominal speed of 3000 rpm, the unit delivers a continuous torque of 6.7 Nm while drawing 18.2 A of standstill current. The motor has a torque constant of 0.41 Nm/A, and it can handle peak pulse currents up to 137 A during short acceleration events. Heat is removed through natural convection, so the housing depends on unobstructed airflow instead of forced cooling. Rotor inertia moderates speed changes, which can help smooth motion on axes with changing loads. Power enters through a connector on side A, and incremental encoder feedback returns position data to the drive so the control loop can respond to commanded movement. Because the motor does not include a blocking brake, the shaft must be held by external means when power is off.

The stator windings have an inductance of 2.0 mH and a resistance of 0.38 Ω, values used by the analog drive for current regulation. An integrated shaft seal works with the IP65 enclosure to protect the bearing region from contaminants and water jets on the factory floor. The motor weighs 18 kg, reaches thermal equilibrium in about 60 minutes, and can operate up to 1000 m above sea level without derating. Its mass and thermal behavior should be considered when the motor is mounted on moving carriages or compact machine frames.
