Product Description:

The MAC112D-2-HD-4-C/130-A-0/WI520LX/S005 is an AC servo motor produced by Bosch Rexroth Indramat within the MAC AC Servo Motors series. Intended for analog drive systems, the unit converts commanded current into controlled torque and speed for positioning tasks in automated machinery. Its construction supports side-mounted connectors, an external cooling fan, and encoder-based feedback so the drive controller can close position and speed loops accurately.

Mechanically, the motor follows the size code 112 and the length code D, giving the housing a balanced profile for medium-inertia loads while allowing a centering diameter of 130 mm for repeatable flange alignment. Heat is removed through axial surface cooling; an auxiliary blower powered at AC 115 V moves air along external ribs so continuous operation can proceed without thermal derating. Under nominal excitation, the rotor reaches 1500 rpm, a speed that matches many 50/60 Hz mechanical transmissions. The electromagnetic package uses winding code HD, indicating copper section, resistance, and inductance values for 24 A class analog amplifiers. No additional heat sinks or spacers are required for installation.

Functional interfaces are arranged for straightforward wiring. The motor has no blocking brake, so holding torque must come from external clamping or the drive itself. Shaft torque is transmitted through a DIN 6885 keyway, and three-phase power enters through a connector on side A to separate power lines from signal leads. Position is reported by an incremental encoder with standard mounting, and the motor can also accommodate tacho feedback or an absolute encoder according to application requirements. The tacho generator produces 3 V/1000 rpm with standard tacho quality, giving the analog controller a proportional speed signal for closed-loop regulation.
