Did you find that the motor was heating for no reason? There are many causes of motor heating. New North Motor here to explain the cause of motor heating and troubleshooting steps. 1, the motor room temperature is too high 2. Partial heat dissipation...
Synchronous motor is characterized by constant speed, motor rotation n, speed and magnetic field magnetic pole pair p, frequency f, there is a strict relationship between: n = 60f / p, when the magnetic pole logarithm p is determined, the motor speed...
Description of content: In order to start normally, the starting frequency should not be too high, and gradually increase the frequency when the motor starts. If the pulse frequency is too high at start-up, the speed of the rotor cannot keep up with ...
Most of the mixer motor adopts multi-stage motor, adopts direct-connected structure, low energy consumption and high efficiency; the impeller is precision-cast or stamped, with high precision and large thrust. The mixer resumes operation after contin...
Introduction: In order to make the motor the most efficient in use, the capacity and model of the motor must be reasonably selected according to the different properties of the load. If the motor capacity selection is too large, it will not only caus...
Regardless of the form of the frequency converter, different levels of harmonic voltage and current are generated during operation, so that the motor operates under non-sinusoidal voltage and current. Rejecting the data introduction, taking the sinus...
1.Type selection Which kind of motor type should be selected on the one hand, on the one hand, according to the mechanical characteristics of the motor, the starting function, the speed regulation performance, the brake preparation, the overload capa...
Since the inverter is powered, the motor can be started at a low frequency and voltage with no inrush current, and can be quickly braked by various braking methods provided by the inverter, in order to achieve frequent starting and braking. The condi...
