What is a Three-mode controller? Quiet start(Except for special circumstances) strong power and power saving. The three-mode controller is a sine wave controller. It can operate in three modes, sine wave mode, square wave mode, and no hall mode (that is, it can be used without a hall sensor). The mode cannot be selected, the default is sine wave mode. When the hall sensor is damaged it will automatically switch to square wave mode. Runs no-Hall mode when no Hall sensors are connected. Suitable for in-wheel motors.Differential motor, etc. Tips: Applicable to a variety of motors, but only in-wheel motors with Hall sensors can use sine wave mode. When running other motors, it will automatically switch to square wave mode or no Hall mode.
