Embodiments herein include electronically commutated (“EC”) motors, fans operated by such motors, cooling systems including the same, and related methods. In an embodiment, an electronically commutated fan motor is included. The fan motor can include a housing comprising an exterior wall, a shaft, a shaft drive assembly rotatably coupled to the shaft, a power input connector, a control input connector, a switch comprising a base and an actuator accessible outside the housing, the actuator comprising a first actuator position and a second actuator position. The fan motor can also include a controller configured to control the shaft drive assembly based on a control signal from the control input connector, a power signal from the power input connector, and a switch signal from the switch. Other embodiments are also included herein.
