Abstract: An electric motor for a pump includes an AC line-in node for receiving AC power supplied to the electric motor. The electric motor includes a current sensor coupled to the AC line-in node and measures current supplied to the electric motor. The electric motor includes a motor controller configured to convert the AC power supplied to a variable frequency variable voltage power for driving the electric motor at a normal output value. The motor controller includes a microcontroller and an inverter. The microcontroller is coupled to the current sensor and receives a measured value of the current supplied to the electric motor, determines the measured value is above a threshold, and transmits a control signal representing a reduced output value. The inverter receives the control signal and generates the variable frequency variable voltage power to reduce output from the electric motor according to the reduced output value.

Abstract: A control system for a pump motor includes a first portion disposed outside a housing of the pump motor. The first portion may include a wireless communication interface and a processor. In some embodiments, the processor of the first portion is configured to control the wireless communication interface to receive a user input from a user device, and generate a control signal in response to receiving the user input. The control system also includes a second portion physically separate from the first portion and communicatively coupled to the first portion. The second portion may include a processor configured to receive the control signal from the first portion, and control the pump motor in response to receiving the control signal.
