Product Description:

MAC112B-1-LD-4-C/130-A-1/DI524LX is a Bosch Rexroth servo motor from the MAC product range. It is designed for surface cooling. The motor is equipped with an axial cooling fan the increases airflow across the operating motor. As a result, the AC motor delivers higher output torque and current compared to motors designed for convection cooling. The continuous output torque at standstill for the MAC112B-1-LD-4-C/130-A-1/DI524LX motor is 29 Nm and the output current at standstill is 43.5 Amps. In contrast, the same motor designed for convection cooling delivers significantly lower output: 17.5 Nm output torque and 26.3 Amps output current. Speed rating of the servo motor is 2000 RPM. Its torque constant at 20 degrees Celsius is 0.740 Nm/A. Resistance of the motor windings is 0.260 Ohms at 20 degrees Celsius and the winding inductance is 3.5 millihenry.

Thermal time constant of the motor is 60 minutes. Weight of the MAC112B-1-LD-4-C/130-A-1/DI524LX servo motor is 36 kilograms. The motor has 130 millimeters centering diameter. Another feature of the motor is an optional holding brake rated for 45 Nm holding torque. This brake operates according to the electrical-release principle: the brake releases the shaft on receipt of a 24 Volts DC release signal. Release delay and clamping delay for the brake are 70 milliseconds and 30 milliseconds respectively. MAC motors support tacho feedback for speed and position evaluation. The MAC112B-1-LD-4-C/130-A-1/DI524LX motor is equipped with a standard tacho generator. A tacho generator is a sensor that measures the rotational speed of the motor shaft. This sensor translates the mechanical rotational speed into an electrical signal that can be read to determine the speed of the rotating shaft. housing of the AC motor belongs to the IP65 protection class.
