The main purpose of the BLDCM is to generate driving torque. As the driving power source of electric energy or various machines, the main function of the BLDCM is to convert mechanical energy into electric energy. Under the action of the moment of the mechanical equipment installed with the BLDCM, the position or angle of the object will change. Therefore, according to the definition formula of Archie moment, it can be calculated. That is, torque (T) = power (P) × 9.8/revolution (n), or mutual conversion factor can also be like this: T * revolution / 9.8 = power. We don't want to take Foshan Fuji electromechanical DC brushless motor as an example to show you.
Located at No.1, Yuandong Road, Sunzhuang Town, Hai'an City, Jiangsu Province, Nantong Far East micro Special Motor Co., Ltd. is a large backbone enterprise in the micro special motor industry. It is a motor and electrical production group enterprise integrating scientific research, production, development and operation, mainly serving the machine tool and machinery industries.
In addition to carbon brush in structure, there is no organic carbon brush in the use of BLDCM. The sparks generated in the operation process directly reduce all kinds of interference, and there is not so much friction. In the application of BLDCM, the loss is relatively small. So more and more devices are using BLDCM.
For example, when the power of the selected DC brushless motor is 1000W, and the number of revolutions of the motor is 3000 rpm, according to the definition formula of Archie moment, there is 1000 * 9.8/3000 = 3.27nm, or the moment t of the brushless motor is known, when the power is required, it can be converted as follows: 3.27nm * 3000 / 9.8 ≈ 1000W. This is the calculation formula of the torque of the DC BLDCM. Different types of motor torque have different calculation formulas, such as the torque calculation formula of ordinary asynchronous motor t = 9550 * P / N, we must pay attention to distinguish.
