Application It is suitable for various industries such as packaging, printing, food, textile, and engineering machinery, and different machines and production lines such as CNC equipment, mechanical equipment, grinding machines, milling machines, printing machines, production workshops, and assembly lines. Specifications Color: Grey Reversible: Yes Assembly Required: No Model: M120A-502 Motor Type: Pure Copper Wire Material: Aluminum Alloy, 40cr Alloy Steel Process: Tempering Treatment, Fine Finish, Nitrogen Treatment Reduction Ratio: 1: 80(80K) Motor Speed: 50Hz: 90-1350r/min, 60Hz: 90-1650r/min No-load Speed: 1350r/min Rated Torque: 25NM Shaft Bore Diameter: 14mm/0.55inch Capacitance: 6F Power: 120W Voltage: 220V Total Length of Wire: About 1m/3.28ft Motor Size: 9*9*25cm/3.54*3.54*9.84inch Speed Control Unit Size: 6*10*9cm/2.4*3.9*3.5inch Packaging Size: 28.5*24*12.5cm/11.22*9.45*4.92inch Gross Weight: 6kg/13.23lbs Package Included 1* Gear Reducer Motor 1* Speed Controller Notes 1. Please check the size carefully before ordering. 2. Please connect each wire correctly to ensure that the machine can operate normally. 3. Based on industry standards, to meet the different needs of customers, please note that our motors do not include power cords. You need to purchase a power cord to connect. 4. Please note that the output shaft speed varies at different reduction ratios. The output shaft speed is equal to the motor speed divided by the reduction ratio. 5. Please note that the gearbox has been greased, but you need to refill it yourself after about 100 hours of use. 6. If the motor is lightly loaded and not running for a long period, the controller can be adjusted to 50% of full speed. When the motor is loaded and working continuously for a long time. The controller should not go below 70% of full speed. Because the motor is decelerated by voltage reduction, the torque will also become smaller after voltage reduction and may be overloaded. At this time, due to the increase of current, the heat dissipation will become worse, and the motor will also heat up seriously, which will damage the service life of the motor.
