<p>What are the advantages of <a href="https://www.pm-motor.com/products" rel="noopener noreferrer" target="_blank"><a href="https://www.pm-motor.com/products" target="_blank"><a href="https://www.pm-motor.com/products" target="_blank">permanent magnet </a>motor</a>s</a> in industrial applications?</p><p><br></p><p>1. Good performance of low and medium speed power generation</p><p><br></p><p>At the same power level, the <a href="https://www.pm-motor.com/products" rel="noopener noreferrer" target="_blank"><strong>permanent magnet</strong></a> generator is twice the output power of the excitation generator at idle speed, that is, the permanent magnet generator is actually equal to the power generator of the excitation level.</p><p><br></p><p>2. Simple structure and high reliability</p><p><br></p><p>The permanent magnet generator eliminates the excitation winding, carbon brush and slip ring structure of the excitation generator. The structure of the whole machine is simple, and the excitation winding of the excitation generator is inflammable and fragile, and the carbon brush and slip ring are easy to wear. Failure, reliability is greatly improved.</p><p><br></p><p>3. Can greatly extend battery life and reduce battery maintenance</p><p><br></p><p>The main reason is that the permanent magnet generator adopts the switching rectifier voltage regulation mode, which has high voltage regulation accuracy and good charging effect. Avoid shortening battery life due to overcurrent charging. The initial rectified output of the permanent magnet generator uses a smaller current pulse to charge the battery, and the same charging current has a better charging effect, thereby extending the service life of the battery.</p><p><br></p><p>4. Small size, light weight, high specific power</p><p><br></p><p>The use of <a href="https://www.pm-motor.com/products" rel="noopener noreferrer" target="_blank">permanent magnet </a>rotor structure makes the internal structure design of the generator very compact, and the volume and weight are greatly reduced. The simplification of the permanent magnet rotor structure also reduces the rotor's moment of inertia, the actual speed increases, and the specific power (ie, the ratio of power to volume) reaches a very high value.</p><p><br></p><p>5. Self-starting regulator</p><p><br></p><p>No external excitation power is required. The generator can generate electricity after rotating. When the battery is damaged, as long as the engine is running, the car charging system can still work normally. If the car has no electricity.</p><p><br></p><p>6. High efficiency</p><p><br></p><p>Permanent magnet generator is an energy-saving product. The permanent magnet rotor structure eliminates the excitation power required to generate the rotor magnetic field and the mechanical friction loss between the carbon brush and the slip ring, thereby greatly improving the efficiency of the permanent magnet generator. The average efficiency of the ordinary excitation generator in the speed range of 1500 rpm to 6000 rpm is only 45% to 55%, while the permanent magnet generator can be as high as 75% to 80%.</p><p><br></p><p>7. No radio interference</p><p><br></p><p>The <a href="https://www.pm-motor.com/products" rel="noopener noreferrer" target="_blank">permanent magnet </a>generator has no carbon brush and no slip ring structure, which eliminates the radio interference caused by the friction between the carbon brush and the slip ring. Eliminate electric sparks, especially suitable for working in environments with high explosion risk, and reduce generators. Ambient temperature requirements.</p><p><br></p><p>8. Especially suitable for working in harsh environments with high humidity or dust.</p><p><br></p>
