What's the Difference between Normal Motors, Inverter Duty Motors and Explosion-Proof Motors?

Motor is an indispensable part of the industrial automation and one of the most common electrical equipment in life. It is widely used in various electrical appliances, ranging from washing machines and fans in daily life; For industrial applications, pumping, machinery industry and fluid transfer, etc. Motors are also indispensable when pumps are used. Therefore, it is very important to understand and choose a suitable motor. The following describes the differences between normal motors, inverter duty motors and explosion-proof motors.

Normal Motors

There are many types of motors, according to the type of input power, they can be divided into DC motors, AC motors, etc. DC motors can be further subdivided into brushed DC motor, brushless DC motor(BLDC motor); AC motor includes induction motor and synchronous motor. In brief, DC motor controls the rotational speed through voltage, which is easy to control, but not suitable for high temperature and flammable operating environments. The AC motor controls the rotational speed through the frequency of the alternating current, so compared with the DC motor, it is not easy to control the speed, while it can be used in a high temperature and flammable operating environments.

Inverter Duty Motors

A variable frequency drive (VFD) (a.k.a Inverter) is used to change the frequency of the alternating current, by changing and controlling the speed and torque of the AC motor. Therefore, "variable frequency" refers to the way of driving the AC motor. It can be started and adjusted frequently without maintaining full-speed operation and maximum power. When the motor speed is reduced, the output horsepower will also decrease, thereby achieving high efficiency and energy saving. The system control is also more stable than the normal traditional motor.

Explosion-Proof Motors

Mainly used in operating environments where flammable substances exist, such as coal mining, natural gas industry, petrochemical and chemical industries, etc. With the hard explosion-proof shell, it can sustain the explosion pressure inside the motor, and also can isolate the heat from the inflammable materials, so as to avoid the danger of fire or explosion.

According to the explosion-proof form, it can be roughly divided into flameproof motor (symbol d), intrinsic safety motor (symbol i), increased safety motor (symbol e), positive pressure explosion-proof motor (symbol p), non-sparking motor (symbol n), and dust ignition proof motor, etc., depending on the protection level, each has its features and functions.

With a brief understanding of the differences between these motors, I believe it becomes easier to choose the right motor for your needs.
