I. Product Overview
A brake motor is a special type of motor that integrates both power and braking functions, widely used in automated machinery and equipment that require rapid stopping and precise positioning. As a professional foreign trade company, Taizhou Maotai Electromechanical Co., Ltd. has long-term cooperation with quality factories to supply various high-performance brake motors, meeting the diverse needs of customers worldwide.
II. Classification of Brake Motors
Brake motors are mainly divided into two categories: DC brake motors and AC brake motors.
DC Brake Motors
• Require a rectifier; rectified voltage is 99V, 170V, or 90–108V
• Because the voltage must pass through rectification, the fastest braking time is approximately 0.6 seconds
• Simple structure and low cost
• Heats up quickly and is prone to burnout
AC Brake Motors
• Directly connected to 380V voltage without rectification
• Braking time can be completed within 0.2 seconds
• More complex structure and relatively higher cost
• Obvious braking effect and durable — an ideal power choice for automation control
Important Note: For both DC and AC brake motors, the braking section (i.e., the brake) cannot be connected to variable-frequency voltage and requires separate wiring for synchronous control.
III. Working Principle of Brake Motors
An electromagnetic brake is mounted at the rear of the motor. When the motor is powered on, the brake is energized and engaged simultaneously, exerting no braking force on the motor. When the motor is powered off, the brake is also de-energized and, under the action of springs, brakes the motor for rapid stopping.
Specific wiring method: The two AC input terminals of a full-bridge rectifier are connected in parallel to any two incoming lines of the motor, synchronously inputting 380V AC with the motor; the two DC output terminals are connected to the brake excitation coil. When the motor is powered on, the coil receives DC current and generates magnetic force that separates the two friction surfaces at the rear, allowing the motor to rotate freely. Conversely, the spring return force applies the brake. Depending on motor power, coil resistance ranges from tens to hundreds of ohms.
IV. Application Scope of Brake Motors
Brake motors provide high-precision positioning capability. An ideal brake motor should meet the following requirements:
• Rapid braking
• Accurate positioning
• Safe and reliable
• Interchangeable brake systems
• Simple structure, easy replacement and maintenance
Many factories use brake motors to control motor inertia and achieve the required accurate positioning for automated mechanical operations. Typical application scenarios include: hoisting machinery, ceramic printing machinery, coating machinery, leather machinery, etc. Brake motors are widely used and can be found in virtually every field of mechanical equipment.
