Brake Motor 0.75kW 1Hp

The Brake Motor 0.75kW 1Hp is an electric motor product line with a capacity of 0.75kW equivalent to 1 horsepower, equipped with an additional magnetic brake (electromagnetic brake) at the rear of the motor, used in cases where the motor needs to be stopped when not operating. It belongs to the electric motor classification under 3.7kW and is commonly applied in various mechanical manufacturing industries such as freight elevators, lifting overhead cranes, conveyors, etc.

What is the general design of the Brake Motor 0.75kW 1Hp?

The Brake Motor features an external structure made of cast iron and aluminum housing, coated with a blue electrostatic paint that resists corrosion and prevents agents from the external environment. At the rear of the electric motor, there is a cooling fan to cool the motor during operation and a fan cover protecting the outer fan edge.

Structure of the Brake Motor 0.75kW 1Hp

The device is a tight mechanical and electromagnetic combination between the traditional motor part and the braking system.

• Stator: Formed magnetic steel core, containing pure copper windings coated with class F heat-resistant insulating varnish.
• Rotor: Squirrel-cage rotating shaft made of alloy steel, undergoing dynamic balancing to help the shaft rotate stably without shaking.
• Electromagnetic brake: Braking module mounted at the end of the shaft core, containing a magnetic suction coil, friction disc, and pressure spring, tasked with locking the rotating shaft immediately upon power disconnection.
• Friction disc: Friction-resistant component made of heat-resistant organic material, with heat dissipation grooves on the surface.
• Cooling fan: Centrifugal fan made of plastic mounted behind the brake assembly, continuously pushing cooling air along the body.

What types of 0.75kW 1Hp brake motors are available?

The 0.75kW 1Hp machine line offers four rotational speed levels, suitable for various mechanical transmission systems. Below are the detailed technical specifications.

0.75kW 1Hp 2-pole brake motor (2,800 – 3,000 rpm)

The device rotates at high speed, serving mechanisms that require high revolutions and decisive stopping.

Technical specifications:

Practical applications:

• Centrifugal pumps for domestic water supply requiring quick stopping features.
• High-speed automatic blank pushing mechanisms in small machining workshops.
• Thin cutting tool spindles requiring braking to stop immediately upon cycle completion.

0.75kW 1Hp 4-pole brake motor (1,400 – 1,500 rpm)

The common speed range provides stable pulling force along with smooth braking capability for light loads.

Technical specifications:

Practical applications:

• Light component conveyors needing to stop precisely at inspection stations.
• Batching packaging machines requiring shaft disconnection according to set weight.
• Food hoist mechanisms lifting between floors in small workshops.

0.75kW 1Hp 6-pole brake motor (900 – 1,000 rpm)

The unit features reduced revolutions to increase pulling force, suitable for braking solid loads.

Technical specifications:

Practical applications:

• Cable winding drums of light-load lifting winch equipment.
• Incline conveyors transporting materials requiring anti-reverse drift when power is cut.
• Chemical powder screw conveyor pulling mechanisms into storage tanks.

0.75kW 1Hp 8-pole brake motor (700 – 750 rpm)

The slow-rotating machine line generates good initial pulling force accompanied by a safe shaft locking system.

Technical specifications:

Practical applications:

• Small workshop overhead crane bridges requiring slow traveling speed and position orientation.
• Fixed turntables for automated welding parts requiring precise rotation angles.
• Operation platform lifting mechanisms in assembly workshops.

Which gearboxes can be combined with the 0.75kW 1Hp brake motor?

To change speed and increase pulling force, installers need to connect the 0.75kW motor with compatible mechanical gearbox systems (speed reducers).

• Helical gearbox: R37 inline or K37 right-angle shaft lines containing lubricating oil, specialized for pulling light goods conveyors.
• Aluminum worm gearbox: Using NMRV size 40 or 50 code provides a compact structure for basic lifting mechanisms.
• Transmission coupling: Applying flange couplings or rubber cushion couplings to dampen mechanical vibrations fed back to the shaft when the braking system operates.

Guide on wiring for the brake motor

The 3-phase motor with magnetic brake uses an electromagnetic brake to hold the shaft when stopping the machine. When wiring, it must be done according to the diagram to avoid errors between the motor part and the brake circuit.

Step 1: Check parameters

Check the parameters on the motor nameplate including voltage, power, and rated current. For motors with magnetic brakes, it is necessary to check the brake coil voltage additionally to select the appropriate power source. You can watch the electric motor video to learn how to read these parameters.

Step 2: Open the terminal box

Remove the terminal box cover to check the internal wire ends. This area typically contains the stator wires, power supply ends, and the rectifier board of the magnetic brake system.

Step 3: Identify connection terminals

Based on the motor wiring diagram, identify terminals U, V, W and terminals related to the brake circuit. Do not connect if the function of each wire end is not clearly determined.

Step 4: Connect power wires

Connect power wires to terminals U, V, W according to the diagram. After connection, recheck the wire tightening and contact points to avoid looseness or poor contact.

Step 5: Check operation

Supply power and check that the motor runs and the magnetic brake operates in the correct state. If the brake does not release or the motor runs unstably, check the connections and power supply again.

Besides the wiring section, you can access the summary video section of Thanh Thai Motor. This is a page containing many videos about electric motors according to content groups such as inspection, repair, and operation, not individual wiring guide videos.
