Reasons for the burnout of the miniature DC geared motor

The direct cause of the burn-out of the miniature DC geared motor is high temperature. Common faults of motors are divided into two categories: mechanical faults and electrical faults. Electrical faults include stator and rotor windings short-circuit, open circuit, starting equipment failure, etc.; mechanical faults include: excessive vibration size, bearing overheating, stator and rotor friction, abnormal noise, etc.

When the miniature DC geared motor is overloaded for a long time, the stator current greatly exceeds the rated current, and the motor is overheated. Because the motor starts frequently, the start time is too long, or the start interval is too short, the temperature rise of the motor will basically be too high. There are also mechanical failures being dragged, causing the output of the motor to increase, or to freeze or slow down, resulting in a sharp increase in motor current and overheating, and the working mode of the motor does not match the working system of the load, such as short-cycle work. The built-in motor is used to drive loads that work continuously for a long time.

For the miniature DC gear motors used in special industries, some users lack understanding of the economic benefits brought by the motor system, or have obstacles to the technical problems of energy-saving transformation of the motor system. correct. Like our customers, because they do not understand the characteristics of the miniature geared motors, high-load operation causes high-temperature short-circuits caused by the burning of the machine. Professional manufacturers must customize geared motors with matching power for enterprises to make the products more durable and stable.
