Differences between Brush Generator and Brushless Generator

The commutation of the brush DC generator is always realized by contacting the graphite brush with the annular commutator installed on the rotor. The brushless generator feedback the rotor position back to the control circuit through the Hall sensor, so that it can know the accurate time of the generator phase reversal.

Most brushless generator manufacturers produce generators with three Hall effect positioning sensors. The brushless generator has no brushes, so there is no relevant interface, so it is cleaner, has less noise, in fact, requires no maintenance, and has a longer service life.

In the last three decades, the research on variable frequency speed regulation of asynchronous motor is to find a way to control the torque of asynchronous motor in the final analysis. Rare earth permanent magnet brushless DC motor will show its advantages in the speed regulation field with its wide speed regulation, small size, high efficiency and small steady-state speed error.

Brushless DC generator is also called DC frequency conversion because it has the characteristics of DC brushless generator and is also a device for frequency change. The international common name is BLDC. The operation efficiency, low speed torque, speed accuracy, etc. of brushless DC generator are better than any frequency converter with any control technology, so it deserves the attention of the industry. This product has been produced more than 55kW and can be designed to 400kW, which can meet the demand of industry for power saving and high-performance drive.

Fully replace the speed regulation of DC generator, frequency converter+variable frequency generator and asynchronous generator+reducer; It can operate at low speed and high power, and can save the large load directly driven by the reducer;

It has all the advantages of the traditional DC generator and eliminates the carbon brush and slip ring structure; Excellent torque characteristics, good middle and low speed torque performance, large starting torque and small starting current; Stepless speed regulation, wide speed regulation range, strong overload capacity;

Small size, light weight and large output; Soft start, soft stop and good braking characteristics can eliminate the original mechanical braking or electromagnetic braking device; High efficiency. The generator itself has no excitation loss and carbon brush loss, eliminating multi-level deceleration loss. The comprehensive power saving rate can reach 20%~60%, and the purchase cost can be recovered one year only for power saving;

High reliability, good stability, strong adaptability, and simple maintenance; Resistance to turbulence and vibration, low noise, small vibration, smooth operation and long service life; No radio interference, no sparks, especially suitable for explosive places, explosion-proof; Trapezoidal wave magnetic field generator and forward rotating wave magnetic field generator can be selected as required.
