Explosion-proof Motor 0.75kW 1Hp

Explosion-proof Motor 0.75kW 1Hp plays an intermediate role in converting electrical energy into mechanical energy. This electric motor is widely used due to its high safety and minimized risks. Let’s explore the explosion-proof motor in this article!

Overview Design of Explosion-proof Motor 0.75kW 1Hp

Explosion-proof Motor 0.75kW 1Hp belongs to the group of explosion-proof motors under 3.7kW, designed with a durable and sturdy cast iron outer layer. With an improved thick motor housing and larger internal wiring, the motor offers enhanced safety, good impact resistance, and high-temperature tolerance. In particular, Explosion-proof Motor 0.75kW 1Hp also has the ability to prevent explosions in the event of an electrical failure.

Internal Structure of Explosion-proof Motor 0.75kW 1Hp

The internal components of the device are manufactured according to explosion-proof safety standards to minimize risks during continuous operation.

• Stator: The magnetic core is made of technical steel sheets to help reduce power loss. The internal copper winding features Class F insulation, maintaining stable operation as temperature rises.
• Rotor: The squirrel-cage rotor is made of solid steel alloy. This component is dynamically balanced on a computer to reduce physical centrifugal friction and prevent electric sparks during rotation.
• Bearings: The motor shaft uses industrial bearings integrated with dust covers and high-temperature resistant grease, helping the rotating shaft maintain long-term stability.
• Cooling system: The cooling fan attached to the shaft end uses anti-static plastic material, preventing electrical discharge when the fan operates in a dusty environment.

What Gearbox Does Explosion-proof Motor 0.75kW 1Hp Combine With?

To change the traction force, technicians need to assemble the 0.75kW motor with compatible mechanical gearbox drive mechanisms.

• Helical gearbox: Oil-immersed R17 and R27 inline series are used to drive small conveyors.
• Worm gearbox: Hollow-shaft NMRV size 40 or size 50 codes combined with the motor serve light lifting mechanisms.
• Drive coupling: Use heavy-duty rubber couplings or metal couplings with rubber pads to minimize the risk of spark generation due to friction.

Wiring Guide for Explosion-proof Motor

To ensure electrical safety and technical standards, you need to follow these 5 steps sequentially:

Step 1: Cut off power and inspect the equipment

It is mandatory to pull the circuit breaker to completely disconnect the grid power. Preview the electric motor video and carefully read the specifications printed on the motor housing to know the standard voltage level, thereby preparing the type of wire with a suitable cross-section.

Step 2: Remove the terminal box cover

Use a wrench to unscrew the bolts to lift the protective cover (identified by the “EX” symbol) off the machine body. The opening process must be careful not to damage or displace the explosion-proof rubber gasket at the box edge.

Step 3: Locate terminal studs

Observe inside the terminal box to accurately locate the 3 copper studs engraved with the letters U, V, and W. Compare with the diagram to check whether the copper bars are installed in a star or delta configuration to match the existing power grid.

Step 4: Connect power cable and grounding

Crimp cable lugs onto the power cable and fasten them directly to the U, V, and W studs. The strictest requirement in this step is to tighten the screws firmly to thoroughly prevent the risk of sparking. Next, connect an additional cable to the grounding stud position.

Step 5: Close the protective box tightly

Place the cover tightly against the rubber gasket edge, then evenly tighten the bolts at all corners. If you need to refer to the wiring diagrams of other industrial machinery types, look for compilation videos from Thanh Thai Motor.
