You know something about brushless dc motor controller also, because of its long service life, high reliability advantages, is widely used in automobiles, numerical control, aerospace and other industries, specifically what are the advantages of the it? 1, the brushless dc motor controller has good low voltage characteristic, torque overload characteristic is strong, big start torque, small startup current, etc. 2, brushless dc motor controller of high efficiency, high efficiency area is big, the power and torque density, high power factor (COSΦ)Close to 1, the system efficiency & gt; 90%, permanent magnet brushless dc motor controller in any case the rotor are synchronous operation, ac variable frequency motor is frequency control of motor speed controller, is the speed regulation of frequency conversion brushless dc motor controller, motor controller running under synchronous speed, rotor have neither copper loss and iron loss. 3, permanent magnet brushless dc motor controller, now rare earth ndfeb material using high magnetic energy product. As a result, the volume of rare earth permanent magnet brushless motor than three-phase asynchronous motor with capacity reduces a frame number. 4, brushless dc motor controller because has the characteristics of a dc motor controller, also drives the frequency change device, so also known as dc converter, dc brushless motor controller operation efficiency, and low speed torque and rotational speed precision and so on is more good than any of the control technology of inverter, the brushless dc motor based on automatic control type to perform, 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. 5, wide speed range and the motor controller can run tall in the low speed range. 6, overload capacity is strong, can meet the needs of the vehicle bumps blocked. (5) regenerative braking effect is good, when the car downhill or brake motor controller can completely enter a state of generator controller, to recharge the battery, the electric braking effect at the same time, reduce the financial burden on mechanical brake. 6. Motor controller of small volume, light weight, high power, can effectively reduce weight, save a space. 7, motor control system than asynchronous motor controller is simple. 8, no mechanical commutator motor controller, use fully enclosed structure, prevent dust from entering the motor controller, high reliability. Brushless dc motor controller must be equipped with corresponding dc motor controller speed to work, the cost is relatively higher than a brush motor controller, although the cost is high, or with other advantages or make it popular in various industries applications. , Sara rectification time: 2019 -6 -6
