Servo Motor Replacement Parts Glossary | Global Electronic Services

Global Electronic Services provides a complete index of servo motor replacement parts to help you keep your existing motors running and safeguard against downtime by having the right spares available when you need them.

Below are some of the most common replacement parts for servo motors, but we recommend you contact GES directly to secure parts specific to your servo motor. Our trained technicians and specialists can also help you determine which additional parts may be needed based on performance issues, problems and common failure points of your servo motor parts.

Servo Motor Parts: Brakes

Brakes are an integral part of safe servo motor operations because they perform the much-needed tasks of stopping and holding the rotor. Any error here not only can shut down your production and operations, but it also poses a significant safety concern if your brakes fail to operate properly.

OEMs and Global Electronic Services recommend you replace your brakes if your motor is undergoing a repair and there is less than 75% of the life remaining on your brakes. To assist with this, we stock hundreds of variants of spring-applied and electromagnetic brakes for the top servo motor manufacturers.

Additionally, we stock permanent magnet brakes with zero backlashes for meticulous holding applications. Be sure to ask us about all three types of brakes we provide:

  • Spring-Type Brake — Used without electricity springs against a pressure plate, squeezing both the inner and outer plate. The clamping force is transferred to the hub which is connected to the shaft.
  • Electromagnetic Brake — stops and holds a load when electrical power is disconnected. Additional disks can be used to increase torque without changing the size of the brake.
  • Permanent Magnet Brake — works by using a permanent magnet to attract a single face armature. After the brake is engaged the permanent magnet creates lines of flux, which attracts the armature to the brake housing.

  • Roller Bearings — Bearing can handle much greater loads than all other ball bearings although is not ideal for thrust loading.
  • Ball Thrust Bearing — Used for low speed applications.
  • Tapered Roller Bearing — Ideal for large radial and large thrust loads.
  • Magnetic Bearings — Used for high speed devices.
  • Giant Roller Bearings — Used in large heavy applications.

DC Parts

We stock hundreds of brushes, brush caps, brush holders for all of the servo motor manufacturers that we can service. You also get access to servo motor parts stock that includes a complete array of end cap assemblies.
