What can variable frequency speed control motors do to save energy and electricity?

I'm sure everyone knows that motors have a lot of wear and tear, and electricity consumption is also very expensive. But do you know the main places that consume electricity? This mainly includes the gears and rotating bearings in variable frequency speed control motors. Based on existing capabilities and taking various measures to tap into potential, reduce losses, and improve motor efficiency, the first step in energy conservation is to start with material conservation. Increase effective materials and reduce consumption of copper and iron. For high-efficiency motors, the efficiency index is greatly improved. In order to reduce winding loss and core loss, it is necessary to reduce current density and Magnetic flux density properly. Therefore, the cross-sectional area of the conductor and the length of the core correspondingly increase, and for some machine bases, the outer diameter of the punched sheet increases, thereby increasing the effective material consumption. Reasonably control the temperature rise of the motor. Because the temperature rise is influenced by the amount of material used and mechanical loss, while the material remains unchanged, the temperature rise is reduced by increasing the cooling air volume. As the temperature rise decreases, the copper losses of the stator and rotor decrease, while the mechanical losses increase. If the decrease in copper losses of the stator and rotor is greater than the increase in mechanical losses, efficiency will increase and efficiency will decrease. Therefore, reasonable control of temperature rise plays a crucial role in improving the efficiency of high-efficiency motors.

Which is more efficient, AC induction motor or permanent magnet synchronous motor?

In industrial and commercial applications, most pumps and fans are driven by AC induction motors. "AC induction motors" are asynchronous motors that rely on current to rotate the rotor.
