WHAT IS DVR MOTOR TECHNOLOGY?

DVR, or Digital Variable Reluctance, is a Switch Reluctant Motor with unique technology developed and owned by Teknatool International.

The motor has a simple structure. Around the outside of the motor are a number of electromagnets. The rotor is an extension of the headstock spindle - it looks like a large toothed shaft. When a magnet is switched on, an intense magnetic field is created and the tooth is pulled to line up with the magnet, then the next magnet is switched on, which forces the spindle to rotate.

All these actions are controlled by its micro computer. Through Intelligent Control, this variable speed motor ‘talks’ to the internal micro-computer constantly monitoring conditions, giving it the edge in comparison tests with a conventional motor.
