Product Description
The MAC112B-0-LD-1-B/130-A-0/DI01250/S001 is one of Indramat Rexroth's average-sized motors designed for delivering reliable torque output at a nominal speed of 2000 rpm. It spans a length of 385 millimeters and features a 130 mm pilot diameter. The pilot diameter for motors describes the length of the segment passing through the motor shaft's center and connecting two points in the shaft side's circular base. MAC AC motors manufactured by Rexroth are all equipped with a special encoder. For this machine, the encoder type is an incremental encoder with shock-damped mounting. Shock-damped mounted motors are best for industrial applications because they are more immune to mechanical shocks and vibrations, thereby providing more accurate measurements.
The MAC112B-0-LD-1-B/130-A-0/DI01250/S001 features a special shaft type equipped with a keyway. Motor shafts equipped with a keyway improve torque transmission for loads featuring key connectors. Although this product model features no blocking or holding brake, various methods can still be implemented to halt or fix the rotor's position. Since no holding brakes are integrated, the MAC112B-0-LD-1-B/130-A-0/DI01250/S001's total rotor moment of inertia is only 0.012 kg(m^2). For its size and weight, this machine has a relatively low rotor moment of inertia, implying that the force needed to rotate the rotor is relatively low.
During standstill or stall conditions, the MAC112B-0-LD-1-B/130-A-0/DI01250/S001 achieves a maximum current draw of 26.3 amperes. The standstill current for machines is an important parameter for effectively designing the protection devices within the system. Based on Rexroth's AC MAC manual, the MAC112B-0-LD-1-B/130-A-0/DI01250/S001 has a torque constant of 0.74 Nm/A. Approximately, the torque constant represents how much the torque increases for every ampere increase in the machine's current. In other words, it takes 1 ampere of input current to increase the MAC112B-0-LD-1-B/130-A-0/DI01250/S001's torque output by 0.74 Nm.
