Product Description:

The MAC090B-1-B/110-A-0-100625/S001 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Designed as a motor for analog drives, it delivers commanded rotary motion to machine axes, material-handling stations, and other positioning modules that still rely on ±10 V velocity or torque references. By combining a sealed housing with a built-in blower and incremental encoder feedback, the unit fits industrial automation layouts that require durable construction and real-time shaft position data. Its layout suits motion systems where the external amplifier performs commutation, speed control, and position correction outside the motor housing. This also makes it appropriate for equipment that still uses analog command interfaces rather than fully digital servo buses.

The motor’s rated operating point is a shaft speed of 2000 rpm, and it can hold static loads with a standstill torque of 10.5 Nm. Producing that torque at zero speed requires a standstill current of 17.4 A, while short acceleration bursts are supported by a peak pulse current of 86 A. Each ampere of phase current produces approximately 0.67 Nm/A of electromagnetic torque, which helps relate current demand to available shaft force. The winding resistance is 0.97 Ω, so continuous-duty copper losses must be considered during drive matching. A nominal phase inductance of 5.1 mH helps smooth current transients, and the stator coils release heat through forced axial surface cooling supplied by the integrated blower.

A rotor inertia of 36×10⁻⁴ kg·m² supports a balance between quick response and load stability, and a 110 mm centering diameter helps align the housing on standard mounting interfaces. The blower operates on AC 230 V and pushes air along the external fins to support axial surface cooling, while the thermal time constant is 45 minutes under rated conditions. The enclosure carries an IP65 protection rating to resist dust and low-pressure water jets. Installation is permitted up to 1000 m above sea level without derating, and the incremental encoder provides continuous position feedback for closed-loop speed regulation and repeatable axis motion in automated equipment.
