Brushless dc motor controller what advantage compared with traditional ac motor controller

brushless dc motor controller what advantage compared with traditional ac motor controller people always have curiosity to new things, brushless dc motor controller, compared with other traditional motor controller is indeed a new motor controller, but in fact has been going around the brushless dc motor controller for a long time, overseas already very mature, the control system of brushless motor is due to the domestic industry started relatively late, the strength is relatively weak, so customer prefer to use mature technology, stable traditional motor controller. But with the speeding up of industrial, industrial transformation and upgrading of industry is imminent, under the condition of electricity load is getting heavier and heavier, energy conservation and emissions reduction is every enterprise needs to attach importance to the important platform. Improved after years of development, the domestic brushless dc motor controller is also gradually mature, due to the nature of the brushless dc motor controller itself, makes the brushless dc motor controller will become an important driving force of the industrial revolution. The brushless dc motor controller what advantage compared with traditional ac motor controller, the following discussion with you. Brushless dc motor controller is compared with ac induction motor controller has the following advantages: 1. Rotor used permanent magnet brushless dc motor controller, high quality ndfeb, excitation current is not required. The same power, dc brushless motor controller can output more torque. 2. Brushless dc motor controller is cancelled after the carbon brush, rotor without additional wear and tear, only bearing itself consumption, smaller temperature, longer life, more energy efficient. 3. Brushless dc motor controller startup, locked-rotor torque, high peak, instantaneous torque to the valve open and close the characteristics of the instantaneous torque required. 4. Brushless dc motor controller output torque is proportional to the working voltage and current. Torque detection circuit is simple and reliable. 5. Brushless dc motor controller is adjusted by brushless drive PWM power supply voltage of the average, which can realize steady speed regulating motor controller. Through PWM way to trim the voltage at the same time, start the motor controller can effectively reduce the starting current is small. 6. Brushless dc motor controller of power supply for dc voltage PWM modulation. Relative to the ac frequency conversion motor controller of sine wave ac power supply, its control of motor speed, drive circuit of electromagnetic radiation, smaller, less harmonic pollution of power grid. 8. Brushless dc motor controller adopts the closed-loop speed control circuit, can be in a constant load torque change speed motor controller. Can realize quick feedback signal, motor controller is more precise operation. Brushless dc motor controller based on brushless drive secondary development can realize automatic operation. 10. Brushless dc motor controller through the low voltage dc drive, low voltage, use more secure. This is brushless dc motor controller advantages compared with traditional ac motor controller part, from these advantages can be seen, brushless dc motor controller is small in size, large torque, long life, energy saving, these are all accord with the advantages of industrial transformation and upgrading, so future brushless dc motor controller will become the new trend for the motor controller industry.
