Information

  Geared motor refers to the integration of reducer and motor (motor), which is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical, medical, beauty, health massage, office supplies, etc. A deceleration transmission mechanism for general mechanical equipment. In our daily use, how to protect the geared motor?

 

  1. Overload (overload) protection: For the overload current of the geared motor, the melting point may not be blown, so a protection device to cut off the overload current should be set up. Thermal relays or thermal trippers of circuit breakers are usually used for overload protection, also known as overload thermal protection. Thermal relays are often assembled with contactors, decompression starters or circuit breakers to form an overload thermal protection device.

  2. Phase loss protection: When the phase asynchronous gear motor is running, it is in a two-phase operation (also known as phase loss operation or "single-phase" operation) due to a certain original disconnection and one phase is missing, which is called phase loss operation or two-phase operation. run. In order to reliably protect the reducer from phase-opening operation, a phase-opening operation protection device should be provided.

  3. Short-circuit protection: When the geared motor has a short-circuit fault, the power supply of the geared motor should be cut off in a timely and reliable manner, otherwise the large short-circuit current will quickly burn the reducer, lines and other electrical equipment, resulting in heavy losses. For the low-voltage reducer below 7:500v, the electromagnetic instantaneous release of the fuse or circuit breaker is generally used for protection.
