1. The motor output is torque
if you need to know the force acting on the tangent of a disk with radius r, just divide the torque by R
the power, mechanical efficiency and power factor of the motor should also be known in the calculation process
if mechanical efficiency and power factor are not considered and the motor power is set to P, then there are:
the "torque" of the motor, and the unit is n & # 8226; M (nm)
the formula is t = 9549 * P / n
P is the rated (output) power of the motor, and the unit is kW.
denominator is the rated speed, and the unit is R / min.
P and N can be found directly from the motor nameplate
n here is 100-200 rpm

2. Hello
the specific process of applying for health certificate is as follows:
1. Two ID cards and one inch bareheaded color photos. Go to the relevant departments (Centers for Disease Control and prevention or health institutions undertaking preventive health examination approved by the Ministry of Health) to get the form, fill in the basic personal information, paste the photos (some places give free photos, ask yourself), Pay the cost of physical examination (the cost varies from place to place. The cost of physical examination in Beijing is 63 yuan)
2. Carry out physical examination one by one, first collect blood (usually before 9 a.m.) and then do anal examination, mainly to check whether there are infectious diseases such as Escherichia coli and hepatitis. If there are anal diseases, explain to the doctor in advance. Then there were routine medical and surgical examinations and chest X-ray
3. Take part in the training at the designated time and place after physical examination. The training cost is 10 yuan, and the price may vary from place to place. The certificate is valid for two years
4. Those who have passed the training and physical examination can go to the relevant places to get the "health certificate".
