Brushless Machines and Drives

Technelec has expertise in all types of permanent magnets and reluctance machines. Our proprietory sensorless electronic control technique delivers robustness and manufacturing cost savings.

Synchronous Reluctance	Switched Reluctance	Flux Switching
Three Phase Stator Robust rotor No magnets, no cage, no brushes Sensorless control	Simple short pitched stator coils Power converter excites each coil in turn	DC field winding acts as filter Electronically controlled armature has no brushes Very low cost sensorless control
Permanent Magnet Brushless DC	Permanent Magnet AC	Hybrid Stepping Motor
Simple permanent magnet rotor Stator coils concentrated on each tooth Sensorless electronic control	Rotor combines permanent magnet and reluctance effect Smooth torque quiet operation Highest efficiency Sensorless vector controlled inverters	Combines permanent magnet and reluctance effect Positioning applications New controllers with energy saving features
