Product Description:
The MAC112B-0-LD-1-B/130-A-1/S001 is an AC MAC motor with frame class 112B, designed by Rexroth Bosch. Rexroth's MAC AC motors function well for servo drive applications, requiring precise control of linear and angular positions during operation. MAC AC motors come with an integrated tachofeedback encoder that measures the rotor's speed and relative position with respect to some reference point. MAC AC motors may also come with surface-mounted fans to keep the motor's temperature within its recommended range. For the MAC112B-0-LD-1-B/130-A-1/S001, however, no surface-mounted fans are present. The machine cools naturally via air convection.
The MAC112B-0-LD-1-B/130-A-1/S001 has an LD winding, which allows the motor to reach a nominal RPM of 2000. During standstill rotor conditions, the motor's effective current is 26.3 amperes. The standstill current gives a good estimation of the magnitude of the transient current expected during the machine's starting period. For this reason, the protection system for electromechanical systems also considers the standstill currents of connected motors. Based on its official documentation, the MAC112B-0-LD-1-B/130-A-1/S001 has a torque constant of 0.74 Nm/A. This constant approximates the rate of change of the output torque with respect to the input current. The value signifies that to increase the motor's output torque by 0.74 Nm, the input current must be increased by one ampere.
The MAC112B-0-LD-1-B/130-A-1/S001 has a centering radius of 65 mm, which is also equivalent to a centering diameter of 130 mm. The machine's shaft has a special keyway that allows form-fitting loads to be connected at the maximum torque transfer possible. The MAC112B-0-LD-1-B/130-A-1/S001 also incorporates a standard blocking brake that holds a rated torque of 45 Nm. Since the machine incorporates a blocking brake, the effective dimension of the motor is 435 mm.
