Product Description:

The MAC090C-0-ED-2-C/110-A-O/S005 is an AC servo motor produced by Bosch Rexroth Indramat for the MAC AC Servo Motors series. Classified as a motor for analogue drives, it delivers precise motion to positioning tables, pick-and-place units, and other industrial axes. The motor mounts to machine frames through a 110 mm centering pilot, and the side-A connector simplifies power routing inside control cabinets. Built-in tachofeedback provides speed data to legacy analogue amplifiers, enabling accurate velocity regulation during production.

Under steady thermal conditions the rotor can hold 10.0 Nm of continuous torque while drawing a continuous standstill current of 35.0 A. The electromagnetic coupling is characterized by a torque constant of 0.31 Nm/A, so drives can predict shaft torque from measured phase current. Low copper impedance, shown by a phase inductance of 0.8 mH and a dc resistance of 0.12 Ohm, enables fast current rise during acceleration but requires drives sized for the associated ripple. Heat produced by those currents is removed through natural convection, and the 60-minute thermal time constant indicates how quickly the winding temperature follows load changes. A rotor inertia of 53 × 10⁻⁴ kg·m² balances dynamic response with stability, and it remains rated up to 1000 m installation altitude. The ED winding code identifies the stator configuration, while the standard tacho type and quality assure consistent speed feedback accuracy.

During transient moves the drive may supply 270 A of peak pulse current, allowing the rotor to accelerate up to its nominal speed of 5000 min⁻¹ without saturation. The housing meets the IP 65 protection category, so dust and low-pressure water jets do not affect internal components when the frame is cleaned in place. Despite the protective design, the motor weighs 23 kg, keeping moving mass moderate for gantry axes and simplifying handling during maintenance. Adequate space around the fins is still required because all heat is dissipated directly to surrounding air.
