Rotor Position Sensor Bearing Unit

Synchronous motors require sensors that can accurately position the rotor to precisely control motor torque and achieve optimal efficiency and dynamic performance. These motors use either direct drive control or sinusoidal control. JOJI rotor position sensor bearing units help optimize motor efficiency with both systems.

Features and Benefits
Unit for Sine-Wave or Vector Control

Provides real-time shaft angular position across the entire motor speed range
Generated signals (Figure 1) are comparable to those produced by a resolver and can therefore be used by motor controller software
Communicates shaft angular position via sine/cosine wave signals
More compact and economical than inductive resolvers
Easy to install (Motor Encoder Unit Installation)
No special shaft or housing accuracy is required compared to inductive resolvers (Motor Encoder Unit Design Considerations)

JOJI can adapt the electronics to the interface requirements of a specific application.
