You can adjust the speed according to different products to achieve the ideal result. It is suitable for the packaging industry, printing industry, textile machinery, food, construction, CNC equipment, machine tool industry, automotive, robotics industry, production plant, elevator machinery, barbecue industry, etc.  Key Features Great Durability: The speed control motor with the all-copper coil is more durable and can last for a long time.  Freely Adjusting Speed: The governor has large torque and a wide range of optional speeds. You can freely adjust the speed according to different products to achieve the ideal result. Stable Running: The finely manufactured parts make the top cover and bottom cover tightly and firmly combined so that the rotor can run stably. Low Noise: The motor governor with effective heat dissipation can bring lower noise to create a quieter environment for you. More Heat-resistant: Integrated reducer has experienced a heat treatment process, which is more heat-resistant and increase a long service life. Details Fan Heat Sink: The built-in fan heat sink makes the motor tail exhaust smoothly to achieve effective heat dissipation to protect the machine and lower noise. Ball Bearings: The rotor is equipped with ball bearings at both ends so that the friction is small and the temperature of friction is low to prolong its service life. Application It is suitable for the packaging industry, printing industry, textile machinery, food, construction, CNC equipment, machine tool industry, automotive, robotics industry, production plant, elevator machinery, barbecue industry, etc.    Specification Model: m5120-4025GN-5K Rated Power: 120W Voltage: AC220V Reduction Ratio: 5K Speed (r/min)：0- 270r/min Safe Speed Range: 190-270r/min Torque (N.m): 3.5N.m Load: ≤3.5kg/7.72lbs in General Shaft Diameter: 1.2cm/0.47inch Motor Size: 16.4*9*7.4cm/6.46*3.54*2.91inch Gearbox Size: 7.4*9*4.1mm/2.91*3.54*1.61inch Net Weight: 4.95kg/10.91lbs Package Included 1 * Motor 1 * Speed Governor 1 * Set Accessories How to Use 1.
