A lot of people don't understand the brushless motor controller with what is the difference between the motor controller, both motor controller is actually common in enterprise production machinery and equipment, its performance, application and functions are quite different. Here is look at the motor controller and the brushless motor controller. 1, motor controller of motor controller is working, the coil and the commutator rotating, the magnetic steel and carbon brush don't turn, is the direction of the coil current changes with the motor controller phase switcher and a brush. In the electric car industry brush motor controller and speed there is motor controller and the low speed motor controller. Have a motor controller and the brushless motor controller has a lot of difference, can be seen from the name on the motor controller the carbon brush, brushless motor controller without carbon brush. 2, brushless dc motor controller is composed of main body of the motor and drive, is a typical mechatronics product. Because of brushless dc motor based on self-control type operation, so not as frequency control of motor speed under overloading starting of synchronous motor controller as plus startup winding on the rotor, also won't generate oscillation and step out when load mutation. 3, have motor controller is a traditional product, the performance is stable. Brushless motor controller is to upgrade the product, the live performance is better than a brush motor controller. But the control circuit is more complex, the aging of the components of screening more strict. Although the long life motor controller control circuit is easy to go wrong. So choose brushless motor controller should pass the strict reliability test to ensure quality. , but as the technology continuously upgrade steps, brushless motor controller technology already quite mature. 4, in the process of practical production, because of the brush a tooth is high-speed motor controller, dc motor controller gear tooth is small, easy to wear and tear, but strength is big, strong climbing ability. The brushless dc motor controller, in use process saves two or three years in exchange for carbon brush. But the process in the control of the brushless motor controller, requires very high accuracy. Moreover, the price of the brushless motor controller controller is higher also. By contrast have no tooth brush dc motor controller, although to replace carbon brush, but to replace carbon brush is very easy, and the motor controller is relatively simple, the control of the motor controller smooth operation, high safety coefficient. 5, have a motor controller refers to the motor controller is a dc input, controls the size of the controller only give it its current can speed; The brushless motor controller is a three-phase ac motor controller, controller to convert the dc to three-phase alternating current (ac), and according to the motor controller in the hall element sensor to commutation motor controller to normal operation. Direct, brushless motor controller than to have brush motor controller started long service life, strong power, but higher than brush controller cost controller. At present, now is brushless controller, a brush has been basically eliminated. Electric vehicle controller is used to control the electric motor controller start, run, kind, speed, stop and other electronic devices at the core of the control device of electric cars, it's like the electric car of the brain, are important components of the electric vehicle. 6, brushless motor controller its speed control system than the cost of a brush with the speed control system of high-speed motor controller, the controller in use are prone to failure. Equipped with brushless motor controller of electric bicycle must to 35 km/hour speed above, can play the best working efficiency. 7, a brush motor controller using the transfer speed and the controller to control, through the gear secondary deceleration and overrunning clutch to achieve electric bicycle 0The infinite speed of 20 km/h. Brush with high gold content high speed motor controller, motor controller reduction gear strength is stronger, good abrasion resistance, reasonable design, so the repair rate is low; Change gears and motor controller and maintenance costs less, effectively reduce the electric bicycle repair costs; And a brush motor controller can be easily human riding by overrunning clutch and the flywheel. At the same time have a motor controller general rotor and the stator are coil winding, rotor with brush electricity, most of the motor controller is this way; And general rotor brushless motor controller is a magnetic material directly processed into, so don't need electricity, general small pump.
