A compact, circular, programmable sinusoidal brushless DC (BLDC) motor controller for direct integration into a cased pump
A compact, but powerful brushless DC (BLDC) motor controller
The task for this project was to develop a very small and low cost brushless DC (BLDC) motor controller which could be directly integrated into a pump but deliver a range of programmable performance options.
The programmable features required for this particular controller including fixed speed options, speed control and startup optimisation. The controller was designed to be sinusoidal in order to deliver the best possible performance from the pump.
The application in question required a single pole brushless DC (BLDC) motor and one of the biggest challenges was to accurately control the motor at the lower end of its speed range. This was accomplished by carefully designing the control stage of the controller to allow for this.
Designed to a tight physical specification
This project is a good example of one of the most underrated aspects of bespoke motor control design, namely the way in which it enables motor controllers (whether brushless DC, stepper or DC) to be designed in a way that enables them to be easily and efficiently integrated into product designs.
The quality management process and the AS9100 manufacturing process helped ensure that the controller met the client’s specifications and will continue to do so time after time.
High quality components ensure full compliance and long term reliable performance
As with all of our motor controllers (whether stock range, modified or bespoke design) this particular controller has been designed to meet strict compliance criteria and in a way which ensures long life and excellent performance.
Whether it’s the power consumption, heat transfer or in built safety features to ensure lasting performance, this controller has been designed to provide exceptional and long lasting performance. Full programmability enables units to be re-used or modified to meet different application requirements and all of the components used within the system can then be safely recycled once the units reach their end of service.
