Encoder systems for CM.. synchronous servomotors and DR2C.. synchronous standard motors
For dynamic control of synchronous motors, the rotor position is still required for the control system. Generally, two systems for rotor position detection are used in synchronous servomotors:
- Resolver
- For rotor position detection
- For speed control
- For positioning
- Reference travel required
- Torque control
- Speed and rotation monitoring
- Absolute encoder
- For rotor position detection
- Absolute encoders for servomotors are generally combi encoders with a real-time channel (sin/cos) for speed control.
- For positioning
- Torque control
- Speed and rotation monitoring
- Reference travel is usually necessary for single-turn encoders.
- Reference travel is not necessary for multi-turn encoders.
