Servo motors are a common type of drive device in electrical engineering and automation, which enables precise position and speed control through a control signal loop. Servo motors with brake function can provide additional safety protection when stopping motion. In this article, we will explore different ways to determine whether a servo motor includes a brake system, ensuring you're making the right choice for your equipment needs.

1. Understanding the principle and function of servo motor brake

The basis for correctly determining whether a servomotor has a brake is to understand the role of the servomotor brake and the interrelationships between the brake system.

A servo motor brake is an electromagnetic braking system that stops the movement of the motor by applying an electric current that causes the brake to generate a magnetic force that holds the brake disk in place. The brake system usually consists of components such as brake discs, brake pads, springs, and electromagnetic coils.

2. Check the Motor Specifications and Model Number

The simply ways to determine if a servo motor contains brakes is to check the motor’s model number or specifications. Most servo motors with built-in brakes will have this feature clearly stated in the product documentation or on the motor nameplate. Manufacturers usually provide detailed specifications for their products, which may include brake options. For example, you may find descriptions like "with brake" or "brake option available." You can also search for the model number online to find the motor's technical datasheet.

Tip: If the motor specifications mention torque holding or "holding brake," it almost certainly contains a brake system.

3. Checking the appearance of the motor

In addition to looking up the model number and specification sheet, you can determine if the motor has a brake by directly inspecting the exterior of the motor. Brakes are usually mounted on the rear or end of the motor and have separate coil and cable connections. Look through the motor housing to see if there are visible brake-related markings, buttons or switches.

4. Checking the Servo Drive

The servo driver is the core device that controls the operation of the servo motor, and is usually sold and used in conjunction with the motor. Checking the technical specifications and functional parameters of the servo driver can further confirm whether the motor has a brake. In the drive setup interface, you can find the options and parameter adjustments related to brakes.

5. Consult the Manufacturer or Supplier

If you’re still unsure whether your servo motor includes a brake system, the best approach is to contact the manufacturer or the supplier. Since servo motor designs can vary, reaching out to a professional with knowledge of the specific motor model is an effective way to get a definitive answer. Manufacturers can also provide information on whether the brake is an optional add-on or a standard feature for the motor.

Accurately determining whether a servomotor is equipped with a brake is critical to proper use and commissioning.
