Explanation of cooling mode of motor

Fully enclosed fan cooling (TEFC) - the motor is provided with an air cooling of the motor housing, provided by a fan mounted on the motor shaft.

Fully enclosed self cooling type (TENV) - this motor is installed on the shaft of the fan to keep the internal air circulating in order to prevent overheating. No external fan or air cooling device. The shell is suitable for very dirty and polluted air. These motors are radiating through the shell, and the size of the motor is greater than the other housing. Generally used for small horsepower (maximum 7-1/2 horsepower).

Fully enclosed air cooling (TEAO) - the motor adopts an external cooling fan. Air can be supplied by a blower or a separate blower, which is one with the motor. No matter in any working condition, refrigeration continues.

Special case - Pipe - ventilated motor can be used in open or fully enclosed enclosures and can be used in very harsh environments. Air (the user supplied) is used to air the motor through the air duct, and the heat is discharged through the air duct. Internal circulation or external circulation of cooling air. Anti wind and rain motor using open shell ventilation. The structure of the motor makes the electrical components of the motor, the rain, the snow and the particles in the air reduced to a minimum. The external air can be circulated through the motor to achieve the cooling effect. TEFC motor is a self ventilated motor. General TEFC motor protection level is IP54.
