Capacitor component for an electric motor or generator

An electric motor or generator comprising:

• a stator having two coil sets arranged to produce a magnetic field for generating a drive torque;
• two control devices;
• and
• a capacitor component comprising:
• a first busbar;
• a second busbar;
• one or more capacitor elements;
• and
• a housing having a first portion and a second portion, wherein the first portion and the second portion are arranged to extend around an aperture, the first portion includes a section for housing the one or more capacitor elements, the first busbar, and the second busbar, with the second portion extending between a first end and a second end of the first portion;
• wherein the first busbar and the second busbar are housed within the second portion and arranged to extend around the first portion and the second portion of the housing and the one or more capacitor elements are not housed in the second portion, a first power supply terminal is formed at the first end of the first portion and a second power supply terminal is formed at the second end of the first portion;
• wherein the first power supply terminal is coupled to the first busbar and the second power supply terminal is coupled to the second busbar;
• wherein a first conductive layer of the one or more capacitor elements is coupled to the first busbar and a second conductive layer of the one or more capacitor elements is coupled to the second busbar;
• wherein the capacitor component is arranged to be coupled to a power source for providing current to the two control devices;
• wherein the first control device is coupled to a first coil set and the capacitor component and the second control device is coupled to a second coil set and the capacitor component;
• and
• wherein each control device is arranged to control current in the respective coil set to generate a magnetic field in the respective coil set.
