Structure of the Brake Motor 0.55kW 0.75Hp

The structure of the device includes a standard electric motor and an electromagnetic braking mechanism.

• Stator: Steel core stamped from electrical steel sheets to reduce power loss, containing pure copper windings coated with Class F heat-resistant insulating varnish to prevent short circuits.
• Rotor: High-strength cast steel squirrel-cage shaft, thoroughly dynamically balanced to minimize centrifugal force and vibration during rotation.
• Electromagnetic Brake: Braking module fixed at the shaft end, containing an electromagnetic coil, heat-resistant friction disc, and compression spring, responsible for locking the rotating shaft immediately upon power disconnection.
• Rectifier Diode: Electronic device that converts alternating current (AC) to direct current (DC) to supply stable power to the brake assembly.
• Bearing: Centering ball bearing capable of withstanding radial loads, featuring double-sided dust seals and specialized industrial lubricating grease.
• Cooling Fan: Synthetic plastic centrifugal fan mounted behind the brake cover, pushing airflow along the heat-dissipating ribs of the body.

Wiring Guide for the Brake Motor

A 3-phase motor with an electromagnetic brake uses an electromagnetic braking mechanism to hold the shaft when stopped. When wiring, follow the manufacturer’s diagram precisely to avoid incorrect connections between the motor and the brake circuit.

Step 1: Check Specifications

Check the parameters on the motor nameplate, including voltage, power, and rated current. For a motor with an electromagnetic brake, it is also necessary to check the brake coil voltage to select the appropriate power supply. You can watch the electric motor video directly to understand how to read nameplate parameters.

Step 2: Open the Terminal Box

Remove the terminal box cover to observe the internal wiring. This area typically contains the stator wires, power supply terminals, and the rectifier unit of the electromagnetic brake system.

Step 3: Identify Wires

Based on the wiring diagram included with the motor, identify the U, V, W terminals and those related to the brake circuit. Do not wire without correctly identifying the function of each terminal.

Step 4: Connect the Power Supply

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

Step 5: Test Operation

Supply power and verify that the motor runs and the electromagnetic brake operates correctly. If the brake does not release or the motor runs unstably, check the wiring and power supply again.
