New feature - Tracking Controller!
We are pleased to announce a new version of our evaluation kit which includes a new controller with built-in frequency tracking. The user of new Evaution Kit no longer needs to manually adjust the frequency, since the controller will track automatically once the user starts the motor on the toggle switch.
The Tracking Controller is designed as a stand-alone PCB, mounted on top of our existing driver inside the Evaluation Kit driver box.
Operation is fully automatic:
1. When the controller is powered up, it will do a frequency sweep and store the optimal frequency, i.e. the frequency where the supply current is maximum.
2. Later, when the user manually starts the motor, the frequency will be set to the stored frequency and the tracking starts.
3. Tracking continues as long as the motor is running.
4. When the motor is stopped the last frequency is stored in memory to be used next time the motor is operated.
All major parameters for the operation of the Tracking Controller are set in the EEPROM of the controller chip and can be adapted to different motor sizes and customer requirements on request. Please contact info@pcbmotor.com
The Tracking Controller PCB is also available to customers wishing to incorporate the tracking feature in their own drivers or as a part of a custom motor driver. The design of the uses low cost components and is suitable for high volume production.
