Product Description:

The MAC090B-0-JD-1-B/110-A-0/I00625 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Built as a motor for analog drives, it translates drive amplifier signals into controlled shaft rotation for automated positioning tasks on machine tools, pick-and-place stations, and similar equipment. Its permanent-magnet construction and incremental encoder feedback work together to hold commanded speed and position throughout a duty cycle. That feedback arrangement lets the connected drive correct small speed or position deviations during load changes.

During continuous stall operation, the shaft can develop 6.7 Nm while drawing a steady 18.2 A, and this pairing sets the thermal load that natural convection must remove from the housing. The motor has a torque constant of 0.41 Nm/A, giving a direct ratio for current-based control loops. Rated running velocity reaches 3000 rpm, and short acceleration bursts are supported by a peak pulse current of 137 A. Mechanical attachment uses a 110 mm centering diameter, and power is routed through a connector on side A, which simplifies cable layout in multi-axis frames. The model is supplied without a blocking brake, so external clamping or drive torque must secure vertical loads.

A winding inductance of 2.0 mH limits di/dt and shapes the current regulator bandwidth, while a winding resistance of 0.38 ohms determines copper losses at the specified currents. The motor’s enclosure carries an IP65 rating, permitting installation in dusty or splash-prone zones without additional sealing. Dynamic response is further influenced by a rotor inertia of 36 × 10^-4 kg·m², giving a balance between swift indexing and vibration damping. This inertia level helps the motor respond smoothly during repeated indexing moves without abrupt oscillation. With a thermal time constant of 60 minutes and a mass of 18 kg, the frame warms gradually under load, allowing extended operation under natural convection cooling.
