Brushless Linear Servo Motors
The SL Series brushless linear servo motors feature the same slotless winding design made popular by Compumotor's SM and SE Series rotary servo motors. Along with reduced manufacturing costs, the slotless design creates several performance advantages when compared to traditional ironcore and ironless linear servo motors:
- Single-row magnet bar
- Lower cost and weight (compared to ironless design)
- Better heat disipation (compared to ironless design)
- More force per package size (compared to ironless design)
- Lighter weight forcer (compared to ironcore design)
- Lower attractive forces (compared to incore design)
- Less cogging force (compared to ironcore design)
The Linear Motor Concept
The idea is simple enough. Take a conventional rotary servo motor and unwrap it. What was the stator is now a forcer and the rotor becomes a magnet bar. WIth this design, the motor is connected directly to the load. Direct linear motion is achieved without any rotary to linear transmission devices. The direct coupling of the forcer to the load provides these performance benefits:
- High Speeds
- Zero Backlash
- Fast Response
- High Precision
- High Stiffness
- Low Maintenance
