Product Description:
Created by Rexroth Indramat, the MAC071C-0-US-4-C/095-A-1/WI569LX is a MAC AC servo motor offering a high degree of reliability and output. Typically, motors of this type have high overloading capacity and dynamic performance. In terms of cooling, this type of motor may implement natural convection or surface-mounted types. Specifically, the MAC071C-0-US-4-C/095-A-1/WI569LX utilizes natural convection and achieves a nominal motor speed of 2000 revolutions per minute, continuous torque at standstill of 6.6 Nm, and continuous current at standstill of 7.3 A.
The MAC071C-0-US-4-C/095-A-1/WI569LX has a measured windings resistance at 20 degrees Celsius of 1.6 ohms and a windings inductance of 15 millihenries. These parameters are particularly useful for time constant and impedance calculations, which in turn are important for motor protection and wire sizing calculations. The identified maximum pulse current of this motor is 37 A, and it is assumed to be achieved during the starting condition. Motors have high inrush currents at the starting period because they draw more current to overcome the idle shaft. For the MAC071C-0-US-4-C/095-A-1/WI569LX, the thermal time constant is 45 minutes. The thermal time constant of the motor is useful in determining the time it takes to reach at least 63.2 percent of the final steady-state temperature after a change in the operating condition. Generally, a high thermal time constant is preferable for motors because it implies that the motor is less likely to have high temperature fluctuations and to experience excessive thermal stress.
Aside from the mentioned features, the MAC071C-0-US-4-C/095-A-1/WI569LX is equipped with standard Tacho feedback with a standard-mounted incremental encoder. Tacho feedback allows dynamic adjustment of the motor speed by assigning a voltage value proportional to the instantaneous motor speed. Furthermore, this motor is also equipped with a standard blocking brake that can achieve a holding torque of 3 Nm. Finally, the power connector of the MAC071C-0-US-4-C/095-A-1/WI569LX is connected to side A, the side where the rotor shaft is located.
