Product Description:

The MAC115D-1-ES-2-C/130-A-0/S001 is an AC servo motor built by Bosch Rexroth Indramat as part of the MAC AC Servo Motors series. It is intended to interface with analog drive controllers so that industrial axes receive accurate torque and speed commands for positioning, indexing, and speed-regulated motion. The designation points to a frame size 115 housing, a D-length stator, and the ES winding combination, allowing the unit to serve medium-torque stations in transfer lines, pick-and-place gantries, and packaging equipment. The motor is suitable for legacy automation cells that must remain within specified performance envelopes.

The motor relies on axial surface cooling, and an external blower rated at AC 230 V forces air along the housing to remove losses from the stator windings. This cooling method supports continuous operation in machine sections where natural convection alone may not be enough. Because the motor has no blocking brake, stopping torque must be supplied by the drive or by external mechanics. A centering pilot of 130 mm simplifies alignment inside gearboxes or flanges, while the power leads exit through a connector on side A to keep cabling on the drive end of the machine. Under rated excitation, the rotor reaches a nominal speed of 1500 rpm, which suits machinery that synchronizes motion with standard line frequencies and moderate gear ratios.

For velocity feedback, the unit uses resolver-based tacho feedback with a sensitivity of 3 V/1000 rpm, providing an analog signal proportional to shaft speed for the drive control loop. This arrangement lets the drive monitor speed continuously during acceleration and load changes. The armature winding uses code ES, matching the phase resistance and inductance expected by compatible analog amplifiers. With a frame code of 115, the stator diameter balances torque density and thermal capacity, while the D-length stack increases power without enlarging the mounting face. The absence of a blocking brake also reduces inertial mass, which allows faster coast-down when power is removed.
