Brake Motor 0.25kW 0.34Hp

The Brake Motor 0.25kW 0.34Hp is an electric motor product line integrated with a magnetic brake used in applications requiring sudden, complete stops. Belonging to the electric motor category under 3.7kW, this product is designed with an easier-to-use release lever and is widely applied in mechanical manufacturing industries.

What is the design of the Brake Motor 0.25kW 0.34Hp?

This brake motor features an aluminum housing coated with blue paint, providing aesthetic appeal and protection against environmental factors. At the rear of the motor is a cooling fan responsible for cooling the motor during operation, protected by a fan cover against external environmental impacts.

In particular, the electric motor is also equipped with an additional electromagnetic brake system, helping the motor stop completely and quickly, ensuring safety during machinery operation and protecting the user while running the machine.

Structure of the Brake Motor 0.25kW 0.34Hp

The Brake Motor 0.25kW 0.34Hp includes:

• Stator: Consists of a technical steel core to reduce power loss and Class F standard insulated pure copper winding (heat resistant to 155°C).
• Rotor: One-piece cast squirrel-cage steel shaft, thoroughly dynamically balanced to eliminate vibration and ensure smooth operation at high speeds.
• Electromagnetic brake: Mounted at the shaft tail, including a magnetic coil, friction disc, and compression spring. Responsible for locking the rotating shaft immediately upon power cutoff, preventing load drift.
• Rectifier diode: Placed in the terminal box, responsible for converting AC to DC current to supply stable power to the brake magnetic coil.
• Bearing: High-load-capacity centering ball bearings with double-sided dust seals and specialized industrial grease to increase lifespan.
• Cooling fan: Plastic centrifugal fan mounted behind the brake cover, blowing air along the heat-dissipating ribs to cool the motor during operation.

What types of Brake Motor 0.25kW 0.34Hp are available?

The product is divided into 4 types based on rotational speed.

Brake Motor 0.25kW 0.34Hp 2 poles (2,800 – 3,000 rpm)

Used for mechanisms requiring high rotational speed and fast shaft braking.

Technical specifications:

Practical applications:

• Small-scale woodworking machinery systems requiring immediate cutting shaft braking to ensure operator safety.
• High-speed automatic blank feeding mechanisms in mechanical processing workshops to position materials at pre-programmed coordinates.
• Edge-trimming cutter spindles requiring brake stopping at the end of the cycle to avoid tearing the edges of the processed workpiece.
• Small-capacity centrifugal exhaust fans requiring a shaft locking feature upon power interruption to prevent outside wind from reverse-spinning the blades.

Brake Motor 0.25kW 0.34Hp 4 poles (1,400 – 1,500 rpm)

Provides standard tractive force and speed for light loads.

Technical specifications:

Practical applications:

• Electronic component conveyor systems requiring precise stopping features at optical inspection stations.
• Food hoist elevators lifting between floors in processing workshops requiring a shaft locking mechanism to keep the cage from drifting when stopped.
• Rotary shafts of automatic quantitative packaging machines requiring definitive motion cutoff according to the weight or volume set on the central controller.
• Drive mechanisms for paint or chemical mixers requiring fast shaft stopping to add additives according to the correct timing cycle.

Brake Motor 0.25kW 0.34Hp 6 poles (900 – 1,000 rpm)

Low-speed line with higher torque to pull heavy loads.

Technical specifications:

Practical applications:

• Cable winding shafts of light-duty equipment lifting winch assemblies in warehouses requiring safe brake-holding capabilities when hanging loads at heights.
• Inclined conveyor systems transporting materials or agricultural products requiring brake-locking features to prevent reverse drifting during sudden power outages.
• Bucket elevator drive mechanisms lifting loads to storage bins in small-scale material mixing stations requiring precise stopping at the discharge gate.
• Viscous material agitators requiring high torque at low speeds and immediate stopping when opening the mixing tank lid to ensure operational safety.

Brake Motor 0.25kW 0.34Hp 8 poles (700 – 750 rpm)

Has the slowest speed, high torque, and safe shaft braking.

Technical specifications:

Practical applications:

• End-beam traveling motors of workshop crane systems requiring extremely slow speeds and precise cargo dropping position positioning.
• Fixed turntables for automated robotic welding details requiring high rotational angle accuracy and zero shifting while the welding robotic arm is operating.
• Platform lifting mechanisms for workers in mechanical equipment assembly workshops requiring solid brake locking to ensure absolute occupational safety.
• Rotary kilns for drying agricultural products or powdered materials requiring smooth, even rotation speeds and position brake holding during cleaning of the drying drum.

What gearbox is compatible with the Brake Motor 0.25kW 0.34Hp?

Depending on the required output speed requirements, the 0.25kW motor can be coupled with the following gearboxes:

• Helical gearbox: Model R17 inline shaft. Oil-immersed type, smooth running, high efficiency. Commonly applied for light-duty conveyors and packaging machines requiring precise stopping.
• Aluminum housing worm gearbox: Model NMRV size 30 or size 40. Advantages include ultra-compact size, good self-locking, and easy installation in narrow spaces. Widely used for food hoists, small grinders, and small mixers.
• Coupling mechanism: Use rigid flange couplings or rubber-buffer couplings (preferring rubber types for dampening and absorbing sudden braking shocks, protecting the gearbox).

Wiring instructions for the brake motor

The 3-phase motor with a magnetic brake uses an electromagnetic braking mechanism to hold the shaft when stopping the machine. When wiring, follow the correct diagram to avoid incorrect connections between the motor and the braking system.

Step 1: Check parameters

Check the parameters on the motor nameplate including voltage, power, and rated current. For motors with magnetic brakes, check the brake coil voltage additionally to select a suitable power supply. Watch the electric motor video directly to understand how to read parameters on the motor.

Step 2: Open the terminal box

Remove the terminal box cover to check the internal wires. Inside, there are usually stator wires, power supply leads, and a rectifier for the magnetic braking system.

Step 3: Identify wire leads

Based on the motor’s electrical diagram, identify the U, V, W leads and leads related to the brake circuit. Do not wire without clearly determining the function of each lead wire.

Step 4: Connect power supply wires

Connect power wires to terminals U, V, W according to the diagram. After wiring, re-check wire tightening and contact points to avoid looseness or poor contact.

Step 5: Test operation

Apply power and verify 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.
