Product Description:

The MAC115B-0-GS-4-C/130-A-1/WA605XX/S001 is a servo motor manufactured by Bosch Rexroth Indramat for the MAC AC Servo Motors series. It is specified as a motor for analog drives and supplies precise torque and speed control to industrial axes that require repeatable positioning. By combining the GS winding with an integrated tachometer, the unit suits drive controllers that operate on analog velocity or current loops, making it suitable for packaging machinery, printing lines, and handling stations.

The motor has a frame size of 115 and a length code of B, giving it a shorter stack length that helps reduce the required installation space. Shaft alignment to connected mechanics is aided by a centering recess of 130 mm, while the rotor can reach a nominal speed of 2000 rpm when supplied by the designated drive amplifier. Heat is removed through natural convection, so no additional fan power is required. A standard blocking brake is included, and its holding capability is 45 Nm, which allows vertical or suspended loads to remain stationary when power is off. The GS winding code indicates the electrical resistance and inductance values, and the unit’s standard tacho quality supports velocity loops that do not require extended linearity.

Power conductors are routed through a connector on side A, which simplifies cable entry in machines with limited rear clearance. Torque is transmitted by a shaft machined with a DIN 6885 Keyway. Position and speed information can be supplied through tachofeedback, incremental encoder, or absolute encoder, depending on the selected feedback arrangement. A tacho output of 3 V/1000 rpm aligns with common analog velocity controllers, while the position feedback attachment allows direct coupling to external measuring systems when higher accuracy is required.
