Product Description
The MAC112B-0-LD-1-B/130-A-1/-I01250/S001 is a robust keyed MAC AC motor designed by Rexroth Bosch Indramat. MAC motors with shaft keyways incorporate a metal component that attaches the motor's shaft reliably to a load with a similar connector. Motor shafts equipped with a keyway have better torque transfer profiles and prevent slippage between the shaft and the attached load. For critical applications, motors like the MAC112B-0-LD-1-B/130-A-1/-I01250/S001 may be used to drive gears and pulleys efficiently. The MAC112B-0-LD-1-B/130-A-1/-I01250/S001 has a motor frame type of 112B and weighs a total of 36 kilos (about 79.37 pounds).
Based on the product model's data sheet, the MAC112B-0-LD-1-B/130-A-1/-I01250/S001 has a usable motor speed of 2000 rev/min. The usable motor speed is the average speed at which the motor can reliably deliver the torque and power output. The speed of motors depends on the bus voltage of the motor drive. Generally, a higher DC voltage supply for the drive can increase the motor's speed. However, assuming the rated DC bus voltage speed for the drive, the nominal speed, as stated on the motor's nameplate rating, is achieved. The MAC112B-0-LD-1-B/130-A-1/-I01250/S001 features no surface fans and uses only natural convection to lower its temperature during operation. Considering this cooling mechanism, the machine has a relatively high thermal time constant of 100 minutes.
The MAC112B-0-LD-1-B/130-A-1/-I01250/S001 comes with a standard blocking brake, capable of halting the rotor at a torque rating of 45 Nm. Beyond this torque value, it is not advisable to use the blocking brake. By performing a locked-rotor test, the continuous stall current and torque for induction motors can be obtained. Fortunately, for the MAC112B-0-LD-1-B/130-A-1/-I01250/S001, Rexroth has already done these preliminary tests and identified the continuous stall current and torque as 26.3 A and 17.5 Nm, respectively.
