dongguan brushless motor structure are the same, and most of the motor are rotor, stator, end cover basic parts, such as, winding is also made by permanent magnet and enameled wire, so the brushless motor working temperature and other working temperature of the motor will be different? Just like everyone together to discuss the below.
general motor in high temperature can normal work? How high the temperature of the motor can afford? General motor temperature rise should be below 20 degrees. If measuring the temperature of the motor shell than the environment temperature above 25 degrees, suggests that the rise of temperature of the motor is beyond the normal range, general motor coil is made up of enameled wire winding and become, and enameled wire when the temperature higher than 150 degrees because temperature is too high and fall off of the paint film and the coil short circuit. Motor temperature rise should be below 20 ℃, the temperature of the motor end housing more than the environment temperature should be less than 20 ℃, but what is the cause of the motor for more than 20 ℃ hot? Fever is the direct cause of motor caused by the large current. Generally may be coil short circuit or open circuit, magnetic steel demagnetization caused low efficiency of the motor, normal is electric captain time large current operation.
brushless motor due to the structure and general motors are basically the same, just more than a hall sensor in the reversing internal, so the dongguan brushless motor adjustable working temperature is more than the environment temperature of 25 & deg; Under high temperature is also causes the coil short circuit, the phenomenon such as hall sensor failure. Also note that the environment temperature is generally in 40 & deg; The following, if you want to in 40 & deg; More than the environment temperature of work, need to do special high temperature treatment.
