Torque is proportional to excitation flux and armature current. For example: If you need the machine to drive a 100kg object,knowing the move distance R = 50mm, and the reduction ratio is 1:50, please calculate the torque of the servo motor? The torque formula is given as. If you know the torque of the equipment T2 and the rated speed of the motor n1 and the output shaft speed n2 and drive the equipment system f1 (this f1 can be defined according to the actual operation of the site, most of the domestic 1.5 above) and the motor power factor m (that is, the ratio of work to total work, in the motor winding can be understood as the slot full rate, generally in 0.85). We and our partners use cookies to Store and/or access information on a device. The concept of power is the work done per unit time. Torque = 9550*output power/output speedPower (W) = RPM (rad/s) x Torque (N. m). after the user calculates gearbox output torque, according to the SDT Transmission catalogue, not only the gearbox rated output torque exceed than actual working output torque, but also consider the overload capacity of the drive motor and the required maximum operating torque in practice. You need both horsepower and torque to be able to accurately quantify the performance of an engine. An example of data being processed may be a unique identifier stored in a cookie. Torque is defined as the force applied over a certain distance and is similar to work. For example, suppose you know that the moment of inertia for an object is 10 kgm. What is the function of the rectifier for brake motors? and rpm. In imperial units the Full-load Torque can be expressed as, T = 5252 Php / nr (1), nr = rated rotational speed (rev/min, rpm), In metric units the rated torque can be expressed as, T = 9550 PkW / nr (2). Since most torque problems don't involve making exact measurements, however, you shouldn't have to worry about this. The load is constant power, then T and N is basically the inverse relationship. 88, Minhe Road, Zeguo, Wenling, Zhejiang, China. Binsfeld Engineering Inc.
