12-24V 30A Pypilot motor controller by NaviTop

It is generously sized to provide 30 A continuous current at 12 or 24 V using arranged and sized transistors to deliver 336 A. This allows for very good electrical efficiency for the driver by minimizing losses in the controller.

This nominal current of 30 A corresponds to the motor current at maximum torque when the rudder is turning. This is not the current when the motor is locked, as this controller limits the current when the rudder is locked.

With this calculator, Pypilot reduces the power consumption of the solenoid valve or clutch control coil by a factor of approximately 6. To engage the clutch, the coil is powered at full power for about 250ms. The power is then reduced to what is necessary to maintain the solenoid valve or clutch.

The processor is flashed. For good resistance to the marine environment, the printed circuit board is marinized with several layers of tropicalizing acrylic varnish.

Cable connections are facilitated by Wago connectors:

• 64A lever terminals for power and motor
• 32A lever terminals for clutch control
• 1.5 mm² push-in lugs for the Raspberry Pi UART, rudder angle sensor, and 5V DC output to the ECU.

The enclosure is designed for easy cable attachment using nylon cable ties.
