Controller and circuit board support

A controller, comprising:

• a plurality of circuit boards;
• and
• a support configured to support each circuit board, the support including a plurality of loading surfaces axially spaced from each other and a plurality of fingers extending obliquely relative to the plurality of loading surfaces;
• the each circuit board disposed between one respective loading surface and one respective finger;
• the plurality of circuit boards including a circuit board supporting a sensor and a power electronics circuit board spaced from the circuit board;
• the plurality of loading surfaces including a first loading surface configured to support the circuit board and a second loading surface axially spaced from the first loading surface and configured to support the power electronics circuit board;
• and
• the plurality of fingers includes a first finger disposed between the first and second loading surfaces and extending towards the first loading surface and a second finger spaced from the second loading surface and extending towards the second loading surface;
• the first finger configured to axially bias the circuit board against the first loading surface;
• the first finger configured to elastically deform during installation of the circuit board between the first finger and the first loading surface.
