Product Description
MAC112D-1-FD-4-C/130-B-0/DI524LV/S014 is a Bosch Rexroth industrial motor. It belongs to the MAC product line. A MAC servo system consists of the mains input components, the servo drive module (control unit), the motor cable and the MAC servo motor. The power supply module on the servo system generates the DC link circuit voltage from the AC input voltage. From this the servo drive module generates a three-phase system that is controlled according to amplitude, frequency and phase. This is applied to the MAC servo motor according to the current rotor position and the desired speed. The current amplitude of the three-phase system in the stator of the servo motor determines the resulting torque via the field of the permanent magnet-excited rotor. It results from the system deviation of the speed controller. The frequency of the three-phase system determines the speed of the servo motor.
The rotor’s position and frequency is derived from the signals of the rotor position encoder (BLC signals), depending on the required synchronism between the position of the magnetic field of the rotor and the position of the stator current. The MAC112D-1-FD-4-C/130-B-0/DI524LV/S014 is a feature rich servo motor. Its nominal speed rating is 2000 RPM. Bosch has designed the motor for surface cooling. An axial cooing fan on the motor generates the increased airflow that is required for surface cooling. Power supply requirement of the fan is 230 Volts AC. The MAC112D-1-FD-4-C/130-B-0/DI524LV/S014 motor supports tachofeedback with an incremental encoder that has a shock-damped mounting. An incremental encoder is a type of rotary encoder that converts the angular position of a shaft or axle to an analog or digital code. It does this by generating a series of pulses, or "counts," as the shaft rotates.
