Fractional slot electric motors with coil elements having rectangular cross-sections

A vehicle comprising:

• a power supply;
• and
• a fractional slot electric motor configured to operate using electrical power from the power supply, the fractional slot electric motor comprising:
• a stator core comprising a first side, a second side, and stator slots extending between the first and second sides;
• and
• a coil comprising a plurality of coil elements, each coil element extending through at least one of the stator slots;
• wherein:
• each coil element is coupled to at least one other coil element along the first side of the stator core;
• a first subset of the coil elements includes coil elements coupled to each other along the second side of the stator core;
• and
• a second subset of the coil elements includes loop coil elements, each loop coil element extending from one of the stator slots to another of the stator slots along the second side of the stator core without being connected to other coil elements along the second side of the stator core.

A method comprising:

• obtaining a stator core comprising a first side, a second side, and stator slots extending between the first and second sides;
• and
• forming a coil comprising a plurality of coil elements, each coil element extending through at least one of the stator slots;
• wherein forming the coil comprises:
• coupling each coil element to at least one other coil element along the first side of the stator core;
• and
• coupling a first subset of the coil elements to each other along the second side of the stator core;
• and
• wherein a second subset of the coil elements includes loop coil elements, each loop coil element extending from one of the stator slots to another of the stator slots along the second side of the stator core without being connected to other coil elements along the second side of the stator core.
