Rotor positioning sensor bearing units

  • Rotor positioning sensor bearing units—-Synchronous motors require a sensor to provide high accuracy rotor position for precise motor torque control and to achieve maximum efficiency and dynamics.
  • These motors use either direct drive or sine wave control.SKF rotor positioning sensor bearing units help optimize motor efficiency for both systems.
  • Do a good inspection of the bearing before installation
  • Check the bearing surface for burrs, scratches and cracks before bearing installation.
  • Whether the bearing model number is correct. For example, the model number is YRT50, the inner diameter of the bearing is 50mm, the outer diameter is 126mm, the height is 30mm, the limit speed is 600r/min, etc. All these information can be found on the internet.

Features and Benefits of Rotor positioning sensor bearing units

  • Sine wave or vector control units
  • Provides shaft angular position in real time over the entire motor speed range
    Provides a signal equivalent to that provided by the resolver (Figure 1) and can therefore be used by the motor controller’s software
  • Communicates shaft angular position via sine/cosine signals
    More compact and cost effective than inductive resolvers
  • Easy to install (for mounting of motor encoder units)
    No special shaft or housing accuracy required compared to inductive resolvers (design considerations for motor encoder units)
  • SKF can adapt the electronics to match the application’s interface

FAQ

Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.

Successful mounting is critical to the life cycle of your bearing. Proper bearing dismounting can safeguard other machine components and maintenance workers.

  1. The bearing is at the heart of all rotating equipment, and the condition of the bearing often reflects how well a machine is running.
  2. Learn more about bearing damage and bearing failure – and how to prevent it.

Sure, free samples are available for stock products if you can pay for the shipping cost.

We have regular stock for standard bearings that can be shipped right after your payment. It will take 15-60 days for new production order,which depends on your order quantity.
