Motor torque calculation
Thread Content
I want to build a wheeled robot, but I don’t know how to determine the torque of the DC motor. Last edited by zzg5680 on 2009-1-7 17:14]
The formula for calculating the torque of a DC motor is T=9550P/n, where P is the power in kW and n is the speed in revolutions per minute. The unit of torque is Nm. Of course, it’s possible to measure the motor’s torque using a torque meter; however, this depends on whether there are gears in your robot. If there are gears, it’s necessary to calculate the gear ratio as well before determining the motor’s output torque.
The theoretical (rated) torque of all motors is calculated using this formula.
The original poster can use this calculation, or check a book on electrical engineering
The torque calculation formula for a DC motor is T=9550P/n, and this formula is correct. When the DC motor is operating at its base speed, n equals the BASE SPEED (for example, 900 RPM), and the value of T remains constant. However, when the motor operates above its base speed, i.e., when n > BASE SPEED, the actual rotational speed must be used in place of n (for example, 1150 RPM); in this case, the value of T decreases as n increases, starting from the BASE SPEED value.
By the way, regarding leased land: how is the actual operating torque of an AC motor generally determined?
Below the basic speed of a DC motor, the torque remains constant; above the basic speed, the power remains constant. Different ranges are utilized depending on the control requirements of the respective equipment.
The answer is correct.:victory:
I’ve learned a lot; thank you very much for your discussions and sharing
