Product Description:
The MHD041A-144-PG0-UN is one of the motors in the MHD motor series. This motor from Rexroth Indramat is 2.9kg and has a frame size of 82mm-flange. Its centering diameter measures 50mm in total. The servo motor is categorized as a size “041” and its length is a category “A”. The continuous torque at standstill of this motor is 1.35Nm. It is considered a high efficiency motor with low maintenance cost and high precision control.
The characteristic speed of the MHD041A-144-PG0-UN motor is 7,000rpm and the rated speed is 4,000rpm. The characteristic speed is the speed achieved with a DC link voltage of 540VDC. The continuous torque is approximately ½ what its standard rating is at standstill. The rated speed is the actual speed at which the motor can be used productively. This motor uses conventional cooling. There are two over-temperature ratings for this motor type: one with 60k as the over-temperature point and the other with 100k. The MHD041A-144-PG0-UN motor’s permissible transport and storage temperature range is -20 to 80 degrees Celsius. The maximum permitted ambient temperature is 40oc. It has a mass of 2.9Kg with neither the holding brakes nor fan unit. The rated values for the two motor groups are as follows: For the first motor group, the motor over-temperature is 60.00K, frequency is 200.00Hz, torque is 0.68Nm, voltage is 163.00V, current is 1.29A, and performance is 0.36kW. The second motor group exhibits a motor over-temperature of 100.00K, frequency of 200.00K, torque of 0.89Nm, voltage of 165.00V, current of 1.68A, and performance of 0.48kW..
The MHD041A-144-PG0-UN motor, unlike other motors in the same category, uses a digital servo feedback with an integrated multi-turn absolute encoder. It is ideal where high position precision is desired over a long range. It has a plain shaft and no holding brake, and the direction of the output power and feedback connections can turn 270o. The moment of inertia of the motor is 0.88 x 10-4 kgm2 and it has a maximum speed of 7,500rpm. It has a theoretical maximum torque of 5.6Nm, a winding inductance of 13.5mH, and a peak current of 15.8A.
