An example system includes: an electric motor; a mechanical device coupled to, and actuatable by, the electric motor; and an electronics module comprising: (i) a motor controller controlling the electric motor, and (ii) an actuator board that is electrically coupled to the motor controller, wherein the motor controller is removable and replaceable, wherein the actuator board remains attached to the system when the motor controller is removed and replaced, wherein the actuator board comprises (i) a memory storing one or more settings associated with the electric motor, or (ii) an identifier, wherein when a replacement motor controller is electrically connected to the actuator board, the replacement motor controller receives the one or more settings from the memory of the actuator board or receives the identifier, which allows the motor controller to retrieve the one or more settings.

The present invention relates to a deflector cover for a rotating electric machine, comprising a suction region (120) forming an annular crown (121) comprising at least one body portion (122) and a plurality of air passage openings (123), through-going and distributed throughout the surface of the annular crown (121), forming a structure in the form of a perimeter grid and at least one radial opening (124) comprising a frame (125) with attachment points (126). The present invention also relates to a modular self-ventilated set for deflector covers, a modular forced ventilation set for deflector covers, a rotating electric machine, a method of converting the ventilation mode of a self-ventilated rotating electric machine to a forced ventilation mode and to a method of converting the ventilation mode of a rotating electric machine from forced ventilation to a self-ventilated mode.

Methods for repairing electric machines, such as wind generators, and stators implemented thereof. One method includes replacing a first stator core with a second stator core, wherein the second stator core has fewer stator slots than the first stator core, and wherein the stator slots are configured to receive coil windings. The method includes increasing a number of coil turns forming each coil winding from a first value to a second value, wherein the first value is associated with the first stator core and the second value is associated with the second stator core. The electric machine with the second stator core has rated power output at least as high as the electric machine with the first stator core.

Disclosed is a powered transport cargo system, and a method of retrofitting a powered transport cargo system that includes braking rollers. The method includes replacing a power drive unit (PDU) of the powered transport cargo system with a PDU including a permanent magnet motor (PMM), and removing a braking roller from the powered transport cargo system.

A housing for a crankshaft starter generator is designed so as to be divisible and/or a crankshaft starter generator without a housing and with a stator is designed so as to be divisible.

A blower motor assembly having a variable speed motor that is suitable for replacing a PSC motor in a residential HVAC (heating, ventilation, and air conditioning) system. The blower motor assembly includes a variable speed motor and motor controller; a first power input for receiving a plurality of AC power signals from a control device for use in determining an operating parameter for the motor; and a second power input for receiving AC power from an AC power source for powering the motor controller even when no AC power signals are received by the first power input.

The present disclosure relates to a stripping tool, a method to strip a conductor bar, and an arrangement for stripping a conductor bar from a slot of a core of an electric machine. The disclosure provides a device and a method to facilitate the removal of a conductor bar out of a slot of an electric machine. A stripping tool for removing a conductor bar out of a slot of a core of an electric machine is described, with a piston and a support to apply the piston to the core, a rope to be wound around the conductor bar, and a puller suitable to move the rope vertically to the core to pull the conductor bar out of the slot by means of the rope. Also disclosed is a method to strip a conductor bar out of a slot of a core of an electric machine.

A housing for a crankshaft starter generator is designed so as to be divisible and/or a crankshaft starter generator without a housing and with a stator is designed so as to be divisible.

Systems for replacement of the neutral ring of a rotating electric machine, such as a doubly-fed induction generator (DFIG) useful in a wind turbine, and methods for up-tower repair of the neutral ring. The system generally includes a neutral ring having first, second, and third ring sections formed or two or more laminated layers of copper, and first, second, and third neutral ring connector formed of solid copper. Each of the first, second, and third neutral ring connectors include a cup-shaped fixture extending radially outward from the neutral ring via a riser and are configured for attachment with coils of the winding.

A voltage regulating device for an electric motor has programmable control and regulation circuits carried by a circuit board mounted in a sealed support casing. The circuits have at least one programming terminal which is accessible from outside the support casing to enable programming of the circuits without opening the support casing.
