there are all kinds of brushless dc motor and model, how to choose the right use of brushless dc motor? Here is to explore the brushless dc motor with everyone selection considerations.
the first choice should choose the right voltage brushless dc motor products, according to the customer need to choose the rated voltage to select the drive voltage parameters, pay attention to the use of voltage in the process of no-load and load does not exceed the scope stipulated in the drive.
in the second place, we will choose the peak current drive, select the method of peak current is known input current rating of the motor Ir (一), the peak current Ip (一)≥2 * Ir, otherwise the driver output current in use process without certain engineering allowance, if known to the rated output power of the motor (Or the highest output power)Pr（W)And the driving voltage Vr (V）, the peak current Ip (一)≥4*Pr/Vr。
third, we can also according to the parameters set motor, but we need to set it according to different motor suitable parameters, the use of the, of course, but we also need to be taken into account, the higher the temperature the more wide price.
and brushless dc motor drive brake using short circuit braking motor end, the operation of the motor has brake force, don't work, there is no brake force, the greater the speed, the higher the brake force. Dongguan exterior rotor brushless motor with brake current by current sensing resistors, braking current can't control. So when braking speed cannot exceed safe braking speed, otherwise may burn out power tube, this feature, please use caution.
4, there is also a key is the power of the insulation requirement, to guarantee the normal work of the drive, the hall ground line of the motor and motor winding wire, ground wire winding hall line and straight line insulation resistance can be greater than 100 million & Omega; 500 VDC, able to withstand 600 vac / 50 hz/ma / 1 SEC pressure breakdown.
