What is motor protection? 

Motor protection refers to specialised electric motor components, which are primarily designed to offer protection to an electrical motor against damages, internal faults, abnormal conditions, and other relevant technical and non-technical issues. However, to achieve maximum effectiveness from motor protection, you must choose one that fits your motor's size and voltage level. 

Applications

The major application of motor protection is in synchronous and asynchronous motors, where it is used to manage and protect. Other than these, motor protection is also used for circuit breakers and motors in drive applications as in:

• Pumps
• Fans
• Mills
• Crushers
• Compressors 

Importance

Motor protection components are important for ensuring that the electric motor operates optimally without any hindrance from technical and non-technical problems. They are responsible for protecting against different types of damages that can potentially occur in the electric motor, such as issues involving excess torque or vibrations, startup frequency, control specifications like a short circuit, electric current and voltage, phases, and so on. Without the right motor protection equipment, it is possible that the electric motor won't be able to operate with maximum capability.
