Like other motors, the servo motor will generate electric sparks during operation, which may leave potential safety hazards, especially in inflammable and explosive situations such as coal mines and chemical plants. The servo motor used here needs explosion-proof treatment.
the explosion-proof servo motor is a servo motor with explosion-proof function, which adopts explosion-proof terminal, and the tn-s port adopts professional explosion-proof design scheme, and the motor casing is also made of explosion-proof cast iron raw materials, which has strong safety performance, is not easy to cause spark discharge when in use, and is widely used in places with flammable substances and smoke.
second, what is the price of explosion-proof servo motor?
compared with ordinary servo motor, explosion-proof servo motor has powerful explosion-proof function, and the price is certainly more expensive than ordinary servo motor.
generally speaking, the price of explosion-proof servo motors in the market is mostly between several thousand yuan and ten thousand yuan, and the specific price varies according to the model specifications, power, brand manufacturer, explosion-proof grade and other factors.

III. Principles of selecting and purchasing explosion-proof servo motors
When explosion-proof servo motors are used in inflammable and explosive situations, if inferior products are selected, there will be potential safety hazards. When purchasing explosion-proof servo motors, the following three principles should be followed:
1. Principles of safety and reliability
The types, grades and groups of explosion-proof servo motors should be suitable for the explosive environment used.
2. Principle of economy
The selection of explosion-proof servo motor need not be high. For products of the same level, factors such as price, service life, reliability, operating cost, energy consumption and availability of spare parts should be considered.
3. Principle of environmental adaptability
(1) Under the same conditions, explosion-proof servo motors with simple structure and light weight should be selected, and the system operation requirements should be considered when necessary. For example, intrinsically safe products should be preferred for continuous automation systems.
(2) Select the corresponding electrical explosion-proof type for the hazardous areas that meet the requirements of hazardous locations; If there are both gas and dust in the site, it should be considered to meet the requirements at the same time.
(3) The grade and temperature group of electrical equipment for preventing gurgling should be selected according to the types of flammable and explosive gases/vapors/dust that may exist in dangerous environment.
(4) consider the influence of other environmental conditions on the explosion-proof performance, for example, there are both flammable and explosive hazards in the workplace of dangerous chemicals, and they are also affected by chemical corrosion, or salt spray, or high temperature and humidity, or dust, rain, or vibration.
(5) Ensure the particularity of installation, use and maintenance of dangerous places in petroleum, offshore oil, chemical industry and other industries, for example, there are many types and structures of live equipment, and the installation location is changeable, and the quality of operators and maintenance personnel is different.
(6) choose products with explosion-proof certificate, production license and corresponding national certification.
