Product Description

Featuring a maximum output torque of 18 Nm at a nominal speed of 2000 revolutions per minute, the MAC090A-0-ZD-4-C/110-B-0/WA612XX is a true powerhouse for industrial machines. Designed by Rexroth to be a compact motor, the MAC090A-0-ZD-4-C/110-B-0/WA612XX features no blocking brake and no blower fans for minimal size. During the standstill condition, the output torque of the motor is 3.7 Nm, while its current is 8.1 A. The MAC090A-0-ZD-4-C/110-B-0/WA612XX may operate continuously for a maximum duty cycle of 15 minutes. In the context of motor operation, the duty cycle of the motor represents the time it is on, usually expressed as a percentage of its total operating time. 

Rexroth’s MAC AC motor series manual contains information about the shaft load capacity of the MAC090 motors. The shaft load capacity of the motor has two force components, called the radial and the axial forces. The radial force is the force that is perpendicular to the output shaft, inducing shear stress on the shaft. Meanwhile, the axial force is the force that is parallel to the shaft's axis, inducing compressive stress on the shaft. Based on Rexroth’s documentation, the permissible radial force of the MAC090 motor is dependent on the distance from the point of application of the radial force to the base of the rotor shaft. Following Rexroth’s documentation, the maximum permissible radial force for MAC090 motors operating at a nominal speed of 2000 rpm is around 1100 rpm. Meanwhile, the minimum permissible radial force for MAC090 motors, applied 50 mm away from the shaft, is 900 N. At 50 mm, the permissible axial force is 34 percent of 900 N, or 306 N. 

Like all other motors from the MAC090 family line, the MAC090A-0-ZD-4-C/110-B-0/WA612XX features Tacho feedback. The Tacho voltage for this motor model is 3 volts per 1000 rpm.
