Personally I need to would like to have/develop a high power BLDC controller for an industrial CNC machine.
It has to have the following characteristics:
- 1 to 1.5 kW drive with 110V
- position/speed measurement with quadrature encoder
- Curent/torque/speed/position controlled
- Reinject the power to the power supply
- Controlled using CAN or similar
- Able to block the motor in position
These are high performance requirements but so is the CNC machine.
As price information, the current electronic cost around 25k$ to replace and is based on analog servo controllers.
