Explosion-proof Motor 37kW 50Hp

The Explosion-Proof Motor 37kW 50Hp is an electric motor widely used to convert electrical energy into mechanical energy, helping save electricity and ensuring explosion safety. Let’s explore this product with Thanh Thai Motor!

General design of the Explosion-Proof Motor 37kW 50Hp

Externally, the explosion-proof motor features an eye-catching blue color. The motor housing is made of thick, sturdy, and solid cast iron. Manufacturers place high emphasis on the housing as it plays a protective role, withstanding strong impacts, harsh environments, corrosion, etc.

Additionally, the 37kW 50Hp explosion-proof motor is highly rated compared to other explosion-proof motor lines in the same segment above 3.7kW due to its ability to prevent explosions during electrical faults.

Internal structure of the 37kW 50HP explosion-proof motor

To maintain continuous operation at 37kW power and ensure absolute safety in gas-risk zones, all internal components meet explosion-proof standards (Ex d):

• Stator: Static magnetic core pressed from low-core-loss electrical steel sheets. Pure copper windings coated with a thick insulation layer, multi-layer vacuum varnish impregnation (Class F or Class H) to withstand high temperatures and completely prevent electrical discharge phenomena.
• Rotor: Sturdy one-piece cast squirrel-cage rotating core, surface-machined to be extremely smooth and computer dynamically balanced to completely eliminate mechanical friction causing sparks inside the machine chamber.
• Bearings: Assembled with heavy-duty bearings from world-leading brands (SKF, NSK, FAG). The bearing system integrates multi-layer sealing seals and non-flammable lubricating grease to prevent dust and gas from entering the shaft core.
• Cooling system: Centrifugal cooling fan blades must be made of anti-static plastic or specialized aluminum alloy material so as not to generate static sparks when rubbing against the rear guard cage.

What types of 37kW 50Hp explosion-proof electric motors are available?

The 37kW 50Hp explosion-proof motor product line is manufactured with 4 speed segments to accurately meet the transmission characteristics of heavy-duty industrial systems. Below are the standard technical specifications for each type:

37kW 50Hp 2-pole explosion-proof motor (2,800 – 3,000 RPM)

Technical specifications:

Practical applications:

• Fuel pumping systems: Drives large-capacity centrifugal pumps at filling stations, fuel pipelines, or internal fire pump stations of chemical port warehouses.
• Explosion-proof ventilation: Operates high-pressure centrifugal exhaust fans to discharge toxic gases and supply fresh air to deep coal mining shafts.
• Centrifugal air compression systems: Used for high-speed centrifugal compressors in chemical and synthetic plastic manufacturing plants.

37kW 50Hp 4-pole explosion-proof motor (1,400 – 1,500 RPM)

As the standard and most popular motor line, it delivers a perfect balance between smooth rotational speed and strong torque, ensuring very high durability.

Technical specifications:

Practical applications:

• Industrial compressed air: Drives screw compressor stations to supply power for automation systems in workshops with flammable chemical environments.
• Mineral conveyor belts: Powers steel-corded rubber conveyor systems transporting coal and iron ore from extraction areas.
• Crushers and grinders: Applied in environments with high dust explosion risks in sawdust pellet manufacturing and chemical powder grinding plants.

37kW 50Hp 6-pole explosion-proof motor (900 – 1,000 RPM)

Built with a larger frame size to accommodate more multi-pole copper windings, generating extremely tremendous torque, specialized for continuously handling heavy inertia loads.

Technical specifications:

Practical applications:

• Chemical tank agitation systems: Provides powerful kinetic energy to rotate agitator blades in large-capacity solvent reaction tanks, industrial paints, and chemical adhesives.
• Bucket elevators and ore chain conveyors: Pulls bucket elevator systems lifting stones and ores in steep, humid shafts containing many gases.
• Ball mills: Operates grinding drums requiring continuous dragging force, ensuring no speed drop when fully loaded with raw materials.

37kW 50Hp 8-pole explosion-proof motor (700 – 750 RPM)

Possesses an extremely slow rotational speed, fully converting 37kW into maximum initial torque. The machine housing is designed to be very large (frame 280S) to safely handle the load.

Technical specifications:

Practical applications:

• High-safety winches and cranes: Applied for rig anchor winches, explosion-proof hoists in military weapons and explosive materials storage warehouses.
• Mechanical pressing and stamping machines: Pulls hydraulic scrap metal presses in chemical environments requiring slow RPM and super-large pressing force.
• Drying drums and rotary kilns: Operates chemical drying furnaces and waste treatment rotary drums requiring extremely slow motion and absolute prevention of electrical sparks.

What gearbox does the 37kW 50Hp explosion-proof motor combine with?

Pairing the 37kW explosion-proof motor with transmission equipment requires extremely strict safety factor calculations to ensure the gearbox is not broken under the pulling force of the 50Hp motor.

• Heavy-duty gearboxes (Large R, K, F series): This is the standard solution. Usually utilizes large gearbox codes such as R97, R107 or K97, K107 fully immersed in oil to drive mine conveyor systems.
• Planetary gearboxes: Perfectly combined for hoisting mechanisms and explosion-proof hoists thanks to their ability to withstand super-large twisting forces in a compact size.
• Drive couplings: Mandatory use of hydraulic couplings or ATEX explosion-proof standard steel disc couplings for smooth startup, eliminating mechanical load shock, and preventing friction-induced spark generation.

Instructions on wiring for the explosion-proof motor

To ensure safety and proper technical operations, follow these steps:

Step 1: Check technical specifications

At the beginning of the electric motor video, the instructor will read the specifications of the explosion-proof motor. You need to listen carefully to this part to thoroughly grasp the device information before starting work.

Step 2: Remove the terminal box cover

Use appropriate mechanical tools to remove the bolts. Then, lift the terminal box cover (with the red “EX” letter printed on it) away from the machine.

Step 3: Locate the terminal studs

Once the cover is opened, you will see the copper studs inside. Observe and accurately locate the 3 studs marked with U, V, and W symbols to prepare for electrical connection.

Step 4: Connect the power supply wires

Take the 3 power supply wires (in the illustration, red, yellow, and blue clips) and attach them sequentially to the correct 3 studs U, V, and W identified in step 3.

Step 5: Completion

Thus, you have completed the basic wiring part. If you need to learn more complex wiring styles or refer to other types of machines, search and watch the technical guidance compilation videos produced by Thanh Thai Motor.
