Advantages of Using Servo Motor Brakes

Servo applications often use power-off brakes that hold the overall, driven load for more dynamic braking. You can know more about this application on this site here. In many motion control applications, the servo brakes can decelerate or accelerate a driven system. They are used in many vertical-axis types to hold the load even without the need for power.

The brake is power-off type, spring-applied, and has a 50% static torque that is usually higher than the required hold of the load. On many occasions, the dynamic system assists the motor before abrupt stops or emergencies. The control designers considered the worst-case scenarios that motorists may face on the roads when manufacturing the brakes.

If they overlook the factor of dynamically decelerating, there may be grave consequences that will follow. These results can be a degraded performance, premature wear, or even a disastrous failure.

Operations in the Brakes

In some servo motor applications, regardless if they’re dynamic or static, the brake needs to hold the entire load as everything decelerates, even if electrical power is absent. An excellent servo motor brake can use compression springs to push the armature to stop the rotor in an instant.In disengage brakes, the coil housing has a voltage applied into it, which results in the creation of a magnetic field. This magnetic field will attract the armature and help it axially go to the coil housing. Manual releases are added for a freer rotor if there are power outages.

Advantages of Using Them

Faster Drives and Servo Motors

Many are still debating and comparing hydraulics to servo motors in terms of speed and acceleration. However, many people discover that hydraulics are not the fastest types because they have flexible hoses and oil compressions, where the lines tend to expand.

If the hydraulic designs have more efficiency, they may have a closer edge to the servo system. But for now, the servo drives, and motors are known to be more impressive in the category of speed.


One of the advantages that you have with these systems is their versatility. These mechanisms use error-sensing technologies that make automatic corrections to the products and outputs that a machine produces. Because they can be used in different applications, they tend to make adjustments by themselves after being programmed. Their versatility makes them a valuable investment in conveyor belts, cameras, production lines, cruise control on cars, and automatic doors.

Usage to a Wide Variety of Machines

What comprises the system is also a kind of motor that is used for toy designs. These are called direct current engines that can run from electric batteries. The system is used for opening the doors, sharpening camera lenses, and opening automatic doors. Others have utilized the robotic arms on assembly lines for faster production.

Types to Know About

The servo systems and motors can come in many forms, and they are the following:

  • Linear – These feature a rotation to a given direction, but these types have been installed with more gears.
  • Continuous – These can rotate in every direction possible.
  • Positional – This only rotates in a certain direction, and it’s the most used in many industries

The types are used in various circumstances, and they are widely available. The positional types can be used in smaller projects, while the linear and continuous ones are geared towards larger applications.

Lesser Heat Exerted

The hydraulic machines will let out a lot of heat. Learn more about this machines on this site: This is because it can contain lots of oil, and the design makes it heat more. The servo motors will release the heat in small amounts, and many operators even need to add other systems to keep the oil at a certain temperature.

Less Maintenance on Pump Services

Other differences can be seen between servo motors and hydraulic machines. One of them is maintenance, and it’s generally more cost-effective to maintain a servo system than its hydraulic counterpart. You can cut down costs in the process, and you won’t have to change the pumps more often. It’s important to know that the pumps are more expensive than the system itself, so it’s better to stick to where you can save more.
