Brake Motor 0.37kW 0.5Hp

The Brake Motor 0.37kW 0.5Hp is an electric motor product supported by an additional magnetic brake (electromagnetic brake) used in cases where sudden and complete stopping is required. Belonging to the electric motor segment under 3.7kW, it is designed with a release lever for more convenient use and is widely applied in various mechanical manufacturing industries such as freight hoists, crane lifting systems, conveyors, etc.

What is the design of the Brake Motor 0.37kW 0.5Hp?

The Brake Motor features an exterior structure made of an aluminum housing, coated with a blue electrostatic paint that provides a pleasing visual appearance and protects against external environmental agents. At the rear of the electric motor, there is a cooling fan to cool the motor during operation and an external fan cowl for protection.

In particular, the motor is equipped with an additional electromagnetic brake, helping the motor stop completely for safety during machinery operation and protecting the operator.

Structure of the Brake Motor 0.37kW 0.5Hp

The device structure is a synchronous combination of the basic electric motor part and the electromagnetic brake mechanism.

• Stator: The stationary magnetic core stamped from electrical steel sheets, containing pure copper windings coated with standard Class F heat-resistant insulating varnish.
• Rotor: The squirrel-cage rotating shaft made of alloy steel, undergoing dynamic balancing to ensure stable equipment operation and eliminate centrifugal vibration.
• Electromagnetic brake: A braking module installed directly behind the shaft core, containing an electromagnetic coil, friction disc, and mechanical compression spring system, automatically locking the shaft immediately upon power disconnection.
• Rectifier diode: Electronic component that converts alternating current into direct current to supply power to the brake coil.
• Bearing: Centering ball bearings with good radial load capacity, integrated with dust seals and specialized industrial lubricating grease.
• Cooling fan: A plastic centrifugal fan attached behind the brake assembly, continuously pushing airflow along the cooling ribs of the motor body.

What are the types of the Brake Motor 0.37kW 0.5Hp?

The 0.37kW 0.5Hp brake motor line offers four basic speed ranges, compatible with various low-power transmission systems. Detailed technical specifications are as follows.

Brake Motor 0.37kW 0.5Hp 2-pole (2,800 – 3,000 rpm)

The device rotates at high speed, serving mechanisms that require fast response and definite stopping at high rpm.

Technical specifications:

Practical applications:

• Small-capacity centrifugal exhaust fans that require shaft braking immediately upon power outage to prevent reverse airflow from damaging the fan blades.
• Chemical dosing pumps requiring precise cutoff of fluid flow to control the correct standard mixing ratio.
• High-speed automatic blank rejecting mechanisms in mechanical processing workshops to decisively sort defective products off the conveyor.
• Spindles of small-sized metal polishing machines requiring immediate shaft locking at the end of the polishing batch so technicians can change the cutting disc safely.

Brake Motor 0.37kW 0.5Hp 4-pole (1,400 – 1,500 rpm)

The common speed range provides stable traction and smooth braking performance for light loads.

Technical specifications:

Practical applications:

• Conveyors transferring light components that need to stop precisely at the barcode scanning station for optical readers to record information.
• Food hoists lifting between floors in small-scale processing workshops requiring the cabin to stay stationary during loading and unloading.
• Quantitative packaging machines requiring precise shaft cutoff according to the finished product weight set on the control panel.
• Liquid filling lines for plastic bottles requiring a responsive brake motor so the dispenser nozzle discharges accurately at the volumetric mark.

Brake Motor 0.37kW 0.5Hp 6-pole (900 – 1,000 rpm)

The device features reduced rpm to increase pulling force, suitable for safely braking solid, sturdy loads.

Technical specifications:

Practical applications:

• Cable winding drums of lightweight lifting hoist equipment in confined spaces requiring the feature of firmly holding lifted objects high up.
• Incline conveyors transporting materials requiring a reverse-drift prevention feature during power failures to prevent materials from spilling back to the conveyor base.
• Chemical liquid mixers requiring steady mixing force and shaft locking when opening the tank lid to ensure safety.
• Screw conveyor systems feeding plastic granules into storage hoppers, requiring immediate stopping when sensors report a full hopper.

What gearbox does the Brake Motor 0.37kW 0.5Hp combine with?

To fine-tune the transmission ratio, technicians often couple the 0.37kW machine with specialized mechanical gearboxes.

• Helical gearbox: R17 or R27 oil-immersed codes specially used for light-load conveyor systems.
• Aluminum worm gearbox: NMRV codes size 30 or 40 serving basic lifting equipment in confined spaces.
• Drive coupling: It is recommended to use flange couplings or rubber buffer couplings to eliminate reverse shocks when the brake operates.

Wiring guide 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, follow the schematic correctly to avoid errors between the motor section and the brake section.

Step 1: Check parameters

Check the parameters on the motor nameplate including voltage, power, and rated current. With the magnetic brake motor, it is also necessary to check the brake coil voltage to select the appropriate power supply. Watch the electric motor video directly to learn how to read parameters on the motor.

Step 2: Open the terminal box

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

Step 3: Identify connection terminals

Based on the motor wiring diagram to identify the U, V, W terminals and terminals related to the brake circuit. Do not wire without clearly identifying each lead.

Step 4: Connect the power supply

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

Step 5: Check operation

Power up and monitor the motor running and the operation of the magnetic brake. If the brake does not release or the motor does not run properly, check the wiring and power supply again.
