Let's see why the pmdc planetary gear motor wholesale resistor is abnormal
pmdc planetary gear motor wholesale can promote relatively heavy loads according to high torque and low speed. In the process of use, there will be resistance does not meet the requirements, resulting in abnormal deceleration motor, so what is the reason for the abnormal resistor?
First master the basic principle of the micro reducer equipment: the micro reducer has the premise of the micro motor and the transmission gear reducer, the reducer can reduce the output and input speed of the micro motor and improve the rotation. The motor consists of a motor stator and a motor rotor. The motor stator is a housing and a permanent magnet material that causes an electromagnetic field. The motor rotor, also known as a synchronous motor, is generally cylindrical and is generally made of suppressed silicon steel sheets. The miniature decelerating device has several concave grooves, and the copper core wire is wound in the concave groove. The utility model relates to a small and medium-sized fast motor, which has no iron core winding and generally adopts straight winding winding.
pmdc planetary gear motor wholesale resistor abnormal reason is generally the rotor winding common faults, such as the problem of blocking and winding short-circuit fault, winding component connection abnormal, micro reducer motor coil turns abnormal will also lead to the resistor abnormal.
Micro reducer has the advantage of low speed ratio and large torque, widely used in a variety of load electrical products, in operation, if there is dirty things, the reducer will be stuck, the micro reducer will be blocked, so the micro reducer blocking effect is what?
When the micromotor is transmitted to the AC voltage, the motor rotor is in a resting state because the loaded micromotor cannot be rotated immediately due to the resistance rotation and flexural stiffness. At this time, the micromotor motor stator starting impulse current is about 12 times the rated current. When the operation is blocked, the micromotor gradually rotates, the current is gradually reduced, and the blockage current is subsequently generated, and the operation and plugging current is about 6 times the rated voltage. When the motor rotor speed ratio of the micro-gear motor is at the rated current, the current flow returns to the rated current, and the micro-gear motor is rated to run with double the efficiency of the rated current.
Therefore, when the micro-gear motor is blocked, the current flow will be increased all at once, and the hot will also increase, resulting in a reduction in the service life of the micro-gear motor. If the plugging time is too long, it will directly damage the micro motor.
Small speed ratio motor generally adopts load, short circuit fault, short circuit maintenance. The overvoltage protection of small reducer is generally in the range of 0.5 to 1.5 times the rated voltage. The maintenance posture time and the current size are reversed, that is, the more current, the less maintenance time. However, the maintenance current of the micro-reducer motor should exceed the starting current, and the maintenance posture time should exceed the starting time.
The following experiments can be done: when the miniature reducer is rotating, the clamping shaft and the clamping fast fixture make the miniature reducer forced to rotate, at this time there will be a blocking current, the current is more meaningful than the rated voltage, and the blocking current makes the ambient temperature of the rotor winding rise sharply. The higher the load characteristics and load level of pmdc planetary gear motor wholesale, the easier it is to block frequently after ignition. The mechanical characteristics of pmdc planetary gear motor wholesale, the softer the load capacity, but the blockage at this stage will be small. Reduce the motor is not easy to ignite.
