One or more sensors are mounted on a collar proximate to a motor shaft of a motor. The motor is associated with an electric submersible pump (ESP) located in a wellbore of a geological formation. The one or more sensors sense one or more identifiers located on the motor shaft of the motor. One or more of a rotation direction and rotation speed of the motor shaft is determined based on the sensing of the one or more identifiers. The motor is powered to pump fluid from a reservoir in the geological formation to a surface of the geological formation based on the one or more of the rotation direction and rotation speed of the motor shaft.

A variable frequency drive (VFD) cabinet ventilation system, apparatus and method is described. A VFD cabinet includes an internal air circulating closed circuit that extends through an inside of an air-to-air heat exchanger and an external air open circuit extending around an outside of the heat exchanger. The circulating internal air closed circuit extends through a chamber closed to ingress of external air, the chamber including electrical components of a VFD system. The external air open circuit makes a turn from downwards to upwards before flowing through a VFD chassis including a drive of the VFD system. A VFD cabinet ventilation method includes turning a flow of cabinet ventilation air from downwards to upwards to separate dirt from the ventilation air, passing the separated ventilation air through a VFD chassis, and circulating internal cabinet air through a closed circuit including an inside of a heat exchanger.
