Q: Electric car magnet steel demagnetization should do?: When you buy a car, ask whether it is a high speed motor or a low speed motorHigh speed motor and low speed motor structure is different, the price difference is about 200 yuan, when buying a car, must ask clearly the motor configuration. The structure of brushless motor is similar to that of low speed motor. High speed motor at 400 yuan / more, low speed motor prices at 200 yuan / only

Q: How to select a field effect transistor for brushless DC motor controller for electric vehicle: The function of the FET in the electric vehicle controller is the switch tube, and the popular point is that the control tube of the variable frequency speed regulation is used;

Q: What kind of motor is an electric motor?: In addition, the switched reluctance motor also has great potential as an electric vehicle power, because the switched reluctance motor is lower cost, more reliable structure, and has a very good speed control ability. On the other hand, the efficiency and power density of switched reluctance motor is no worse than that of induction motor (of course, there is still no He Yongci motor ratio), and torque ripple and noise are also the weakness of switched reluctance motor

Q: How do you see whether electric cars adopt low-speed motors or high-speed motors?: In addition, the high speed motor is generally smaller in volume and large in size.Finally, from the car manual can also find some instructions of the motor.

Q: Electric motor car number: SW101100566, what do these figures mean?: Hello In front of you describe the number of letters should be motor motor manufacturers code, is behind the number should be the date in November 10, 00566 natural serial number (motor number), motor nameplate generally has the power of the motor

Q: How to calculate the motor power of electric bicycles?: The motor power of the electric vehicle can be the load power and the no-load powerPower is calculated by testing current and voltage.

Q: The rear wheel of the electric car doesn't move today! Remove the rear wheel, or the motor won't turn! Later, the master said that the two lines in the motor were short circuited. Why is it possible to control the motor when the power line is short circuited?: The short circuit causes the electric energy generated on the motor coil to produce a magnetic field in the motor, which results from the mutual control of the permanent magnetic field

Q: How should the electric motors for disabled people be chosen?: The electric tricycle is provided with energy by the accumulator and driven by a DC motor. The vehicle is easy to operate, smooth, safe, free of pollution and low noise. The disadvantage is that a charging mileage is shorter (about 40 kilometers), charging time is long (about 8 hours), suitable for medium and short distance use.Disabled people should choose the appropriate vehicle according to their disability status, upper limb disability and hemiplegic patients not driving three wheeled motor and electric vehicle; polio patients, patients with lower extremity amputation can use motor or electric tricycle; paraplegia patients and patients with hemiplegia can only use four wheel electric wheelchair.

Q: Can electric motors generate electricity?: Nowadays, brushless DC motor (BLDC) is commonly used in electric bicycles, and the rotor is the permanent magnet,

Q: How high can the electric motor bear the temperature?: Little damage to the motor. The motor generally can withstand 100 degrees. Ultra high load on the battery impact
