Horizontal explosion-proof motors are usually composed of motor body, junction box, bearing box and other components. The motor body is the core component, which is equipped with stator winding and rotor inside, and converts electrical energy into mechanical energy through the principle of electromagnetic induction. In order to connect the motor body with external power supply, control, sensor and other equipment, it is necessary to lead out the power line and control line of the motor through the junction box. The junction box is generally made of cast steel or aluminum alloy, and is filled with explosion-proof clay to ensure the insulation and explosion-proof properties of electrical components. At the same time, in order to ensure the rotation accuracy and service life of the motor shaft, it is necessary to set bearing boxes at both ends of the shaft, with rolling bearings or sliding bearings inside, and grease or lubricating oil to reduce bearing wear and noise. Horizontal explosion-proof motors are usually rigidly connected during installation to ensure the horizontality and stability of the motor. However, this rigid connection method is prone to cause resonance problems, especially when the motor load changes or the external vibration frequency is close to the motor's natural frequency.
