Micromotor production is often used in control systems to achieve the detection, solution, amplification, execution or conversion of electromechanical signals or energy, or to drive mechanical loads. This time, the micro-motor manufacturer specifically introduced the micro-motor production power and various relationships.
The power factor (PF) produced by micro-motors is also called the power factor. The micro-motor manufacturer introduces it as a physical quantity in the AC power system. It is the effective power consumed by the load and its apparent power (the vector sum of reactive power and actual power The module is the apparent power) ratio, which is a dimentionless quantity between 0 and 1.
Micromotor manufacturers introduce that if the load is a linear load, that is, inductance, capacitance and resistance, then the energy may flow back and forth between the load end and the power end, which will reduce the active power.
The micro-motor manufacturer introduced that the power consumed by the pure resistance load connected to the power grid is the same as the received power. The apparent power = active power. However, when the micro-motor is connected to the power grid, the mechanical power output by the micro-motor at all times is inconsistent with the received power. Because the micro-motor needs reactive power assistance when generating mechanical power, the received power (apparent power) = active power reactive power.
Therefore, it is necessary to generate relatively large power, and the loss of micro-motor manufacturers in the process of power generation and transmission will also increase (1KW of power, but because the power factor is 0.2 very low, the power grid needs to supply 5 kVA of apparent power with lines. Although 4Kvar of reactive power will be returned to the power grid in the next cycle, the reactive power will be lost if it comes up and goes over the lines).
Micromotor manufacturers introduced the rated power produced by micromotors refers to the output power of the motor, which is the mechanical power output by the motor, that is, the remaining mechanical power output after the electromagnetic power minus the internal mechanical loss. The micro-motor manufacturer introduced that the rated power is divided by the motor efficiency as the electromagnetic power generated by the motor, and the value obtained by dividing the electromagnetic power by the power factor is the input apparent power required by the motor.
