Product Description:

The MAC090B-0-ND-4-C/110-A is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Classified as a motor for analog drives, it converts regulated drive current into controlled rotary motion for positioning tasks in automated machinery. The design integrates tacho or encoder feedback so the associated drive amplifier can close velocity or position loops without external sensors, making the unit a self-contained actuator for packaging lines, machine tools, and material-handling stations.

Its motion profile starts with a nominal speed of 3000 rpm, which the drive sustains under rated load. From rest, the rotor can deliver a standstill torque of 6.7 Nm while drawing 13.0 A, giving the axis holding capacity against static loads. During rapid indexing, the drive may command a peak pulse current of 98 A. This current is converted into torque by a constant of 0.58 Nm/A. Electrical losses are limited by a winding resistance of 0.75 Ω, while the 3.9 mH inductance shapes current rise time and smooths inverter switching. Natural convection removes the generated heat without external blowers, keeping winding temperature within design limits.

The mechanical envelope and housing protection support integration on exposed production floors. An IP65 housing seals the stator against dust and water jets, and a rotor inertia of 36 × 10⁻⁴ kg·m² gives moderate dynamic response that pairs well with mid-mass loads. Thermal equilibrium changes slowly because the thermal time constant is 60 min, so intermittent overloads have minimal impact on winding life. With an overall length of 520 mm, the motor fits standard 110 mm centering pilots secured by a DS M8-19 spigot thread, while the 24 mm shaft transmits power through keyed couplings. The power connector faces side A, and the standard tacho feedback or absolute encoder option supplies speed data directly to analog servo regulators.
