Product Description

For most MAC AC motors by Rexroth, the holding brake serves as a hold-only brake. Brakes of this type lock the rotor in a fixed position when the rotor speed is zero. In some cases, brakes of this type can also stop a running motor if the stopping energy does not exceed the brake's maximum allowable energy. In some cases, however, a heavy-duty brake may optionally come with Rexroth’s MAC motors. These heavy-duty brakes are sufficient for halting the rotor even at higher running speeds. The MAC092B-0-QD-4-C/095-B-2/WI515LV/S013 is a specific product by Rexroth that features a heavy-duty blocking brake. 

When allowed to operate without loads attached, the nominal rotor speed of the MAC092B-0-QD-4-C/095-B-2/WI515LV/S013 is 2000 rpm. During this condition, the motor draws the rated current to transmit the rated torque and power. At the motor’s stall condition, the current draw increases to 11.9 amperes, while the torque output increases to 7.2 Nm. The maximum holding torque of this motor’s brake is 14 Nm. Like other motors with feedback type 4, the MAC092B-0-QD-4-C/095-B-2/WI515LV/S013 employs a Tacho generator for variable adjustment of the motor position and/or speed. This motor model also uses an incremental encoder that may send signals to a separate motor controller. 

Since the MAC092B-0-QD-4-C/095-B-2/WI515LV/S013 uses natural convection to lessen motor temperature, the original dimensions for this motor model apply. During continuous operation, the motor surface temperature for this product model may reach up to 60 to 100 degrees Celsius. The allowable ambient temperature, as specified in Rexroth’s manual, is 0 to 45 degrees Celsius. Meanwhile, the recommended installation level for this motor model is anywhere less than 1000 m above sea level. Beyond the permissible ambient temperature and installation level range, the motor’s loading capabilities will decline.
