Motor manufacturers reminded that for any product, security is a bottom line of quality, and reliability is the basic requirement for people to deal with purchased products.Three-phase asynchronous motors are used as power supply equipment for machines, and they are widely used, especially in applications on an extraordinary scale. Safety and reliability are particularly important.

　　GB/T 14711 is the standard for safety control requirements for three-phase asynchronous motors. This standard affects the insulation resistance of the motor, the ground insulation of the winding, the phase-to-phase insulation of the three-phase motor, the winding-to-turn insulation, overspeed, overload, protection grade, The situation, period of use and life span have been delineated in detail.

　　The motor manufacturer reminds that the insulation resistance, the grounding of the winding, the phase-to-phase and the inter-turn insulation are the electrical performance requirements of the motor windings. If the three-phase asynchronous motor you purchase is burned out after a period of use, most of the motors have this type of quality. problem.

　　The motor factory, to deal with this problem, takes the type design as the prerequisite, and will conduct inspection and control in the test of motor semi-products and complete products. Motors that fail the test or have hidden dangers will be fully dismantled and reworked to prevent them. Cause losses to customers' use.

　　There is still a greater impact on the safety and reliability of the three-phase asynchronous motor used by customers, the choice of motor protection grade.

　　The protection grade of the motor is to delineate the use scene of the motor, and prevent water droplets or solid foreign objects from entering the motor and causing the motor to be hindered.

　　The problem that often occurs is the mismatch between the customer's selection and the actual operating conditions. For example, the IP23 motor is used in a dusty environment, especially the environment with conductive objects in the dust, which will cause serious damage to the motor windings or even burn the windings. As a result, the motor is hindered in a short period of time.

　　If you know the utilization of the motor but do not know how to choose the protection grade of the motor, you can consult Hubei Wanbang Motor Factory. The senior skilled personnel will answer you online, and can also provide you with a more professional and more customized motor program.
