The open source DiY platform for passionates builder of brushless motor and motor controller.
Controller 80V 400A continue (Improved Vedder VESC full compatible)
ONEmotor controller is 16S high current medium voltage controller with small size (110x40x26mm) designed expecially to place in the back side of my BLDC motor, but usable on many other Brushless and DC motors. It runs with the extremely popular VESC®* firmware. We use only one connector (apart from USB) with a single 20 pin Pico-Clasp connector.
So if you only want PPM control you only fit the PPM wires. Each unit comes with a connector shell and enough pre-crimped wires to populate the whole connector. We leave it up to you to decide which connections you want.
All IO is protected with TVS diodes.The unit can be powered by USB from a laptop to allow tweaking settings without needing to connect main batteries. Wireless chip for control / programming using the VESC®* Tool mobile app.
Max battery cable length without additional capacitors is 1m (Battery wires MUST be short, thick and grouped together, motor wires should be long. So, in case of use my controller outside ONEmotor project please consider best to place controller near battery with long wires to wherever the motor is located. Please be careful when programming settings. Start at low currents and increase step by step. Setting everything at max during initial setup is a bad and really dangerous idea.
I recommend detecting motors using the FOC motor setup wizard. This will automatically find the correct settings for your motor. If you have problems getting your particular motor setup please contact us and we will do our best to help.
If you experience ABS overcurrent faults a lot, then increase your switching speed to 60KHz.
Just turning up the abs max current setting is not a good solution as you are only masking the real reason of the problem.
Please note: High voltage LiPo is extremely dangerous if handled incorrectly. ALWAYS run with a fuse, especially for testing.
