The motor housing must be ventilated and protected:
(1) The motor should be of horizontal (or vertical) structure, and the protection level of the casing should not be lower than IP54. If it is placed outdoors, the motor protection level should be no less than IP55, and it should be protected from rain and dust. The motor should be designed to meet any special torque requirements required for this type of equipment. High-voltage motors require a space heater to prevent internal moisture and condensation when the motor is out of service. The heater is placed inside the motor for easy viewing. The motor shall be installed with a temperature measurement system in accordance with the relevant regulations.
(2) When ventilation is required to establish a barrier, such barriers shall comply with applicable standards and shall be resistant to corrosion. For the ventilation grille, the same anti-corrosion treatment should be carried out as the painted parts of the motor base and the outer casing. In order to inspect and clean the motor windings and air gaps, the grille should be easily removable.
(3) The design of the cooler should ensure that the motor can operate normally with 25% of the pipeline blocked.
(4) In addition to the explosion-proof motor, the motor shall be provided with a discharge port. Explosion-proof motors shall be provided with a safety approved drain plug.
(5) The explosion-proof grade and type of explosion-proof motor shall comply with the requirements of the listed standards.
