Precautions for Selecting Motorized pulleys(Electric pulleys) Motors

The power of the motorized pulleys(electric pulleys) calculated according to the above formula needs to be corrected in the following circumstances:
(1) If the motorized pulleys(electric pulleys) operates continuously for more than 8 hours a day, the motor power should be increased by one grade.
(2) For motorized pulleys(electric pulleys)s with rubber-coated cylinders, the motor power should be increased by one grade.
(3) For motorized pulleys(electric pulleys) motors that start frequently, the motor power should be increased by one grade.

Precautions for using motorized pulleys(electric pulleys) motors
1.Before use, check the oil level inside the roller. The oil level should be about 2/5 of the roller's diameter. Also, check if the motor wiring is correct (Note: When the roller exits, it is in an oil-free state).
2. the roller must be started without load.
3. After the first 300 hours of operation of the roller, change the lubricating oil (lubricating oil grade: N46 for oil-cooled type, N150 for oil-immersed type). Thereafter, change the oil and carry out maintenance and repair every 5,000 hours.
4. Regularly check the oil level and adjust the oil seal spring or replace the oil seal according to the sealing condition
5. In the electrical circuit of the motorized pulleys(electric pulleys), corresponding overload and phase loss operation protection devices should be installed to prevent the motor from being burned out due to circuit faults and causing losses.
6. The motorized pulleys(electric pulleys) should be installed horizontally, with the maximum inclination Angle not exceeding 5°
7. The ambient temperature for the operation of the motorized pulleys(electric pulleys) is -10 ° C to 40 ° C, the material temperature is less than 60 ° C, and the altitude does not exceed 1000 meters. If the working environment exceeds the above range, please contact the manufacturer for a solution.

The usage method of the pulley with backstop
1. The common built-in motorized pulleys(electric pulleys) usually adopts a backstop bearing and is applied to the output shaft end of the motor. When in use, the option can be found by a phase sequence meter or by jog operation (the end cover of the motorized pulleys(electric pulleys) with a backstop all has a rotation direction mark).
2. When the power of the external motorized pulleys(electric pulleys) is less than 30KW(including 30KW), a check bearing is also used and applied to the input shaft end. The motor and the roller are connected by a sleeve type, and the following method can be adopted: The motor and the roller arrow are connected by a split coupling. The coupling bolts can be removed and the motor can be reconnected after being found to be rotating backward.
3. For high-power (above 37KW) motorized pulleys(electric pulleys) motors, other forms of backstop devices are adopted and applied to the roller end covers. For specific usage methods, please contact our factory.
