【Motor wholesale】The key points for the purchase of DC geared motors   Calculation of torque: 1. Know the torque and the output speed of the reducer and the use coefficient, and find the following formula for the motor power required by the motor: Motor power = torque÷9550× motor power, input number of revolutions÷ speed ratio÷ use factor. 2. Know the power and speed ratio of the motor and the use coefficient, and find the reducer torque according to the following formula: Reducer torque = 9550× motor power÷ motor power, input revolutions× speed ratio× use factor.
   Purchase points: 1. Before purchasing, determine the use of DC geared motor, application scenarios, and list environmental requirements, working temperature, backlash and other factors; 2. First of all, determine what kind of reducer is needed, such as small power, high torque, low speed, noise, energy consumption, parameters and other power and performance requirements; 3. Next, determine the output shaft torque, safety and rotation mode, and maintenance mode;   4. Secondly, determine the speed and reduction ratio of the input transmission shaft; 5. Select the motor according to the size of the flange, and if the torque of the output shaft is insufficient, return to the second step to rematch.   Cleaning principle: 1. Ensure that the requirements for the cleanliness of motor parts are met, and in the repair, various different parts have different requirements for cleanliness. When cleaning, different cleaning agents and cleaning methods must be adopted according to different requirements to ensure the required cleaning quality. 2. Prevent the corrosion of motor parts, and do not allow any degree of corrosion to precision parts. When the parts need to be parked for a period of time after cleaning, the anti-rust ability of the cleaning liquid should be considered or other anti-rust measures should be considered. 3. Ensure the safety of operation and prevent fire from polluting the environment.
