The controller is in part received within the control chamber. The controller includes a main electronics board and a modular connector assembly. The modular connector assembly includes a secondary electronics board and a connector at least in part supporting the secondary electronics board. The connector includes an inner connector portion and an outer connector portion. The connector extends through the control housing such that the inner connector portion is disposed inside the control chamber and the outer connector portion is disposed outside the control chamber. The outer connector portion defines a first access portal facilitating access to a first component of the secondary electronics board. ## Claims ### Claim 1 A motor assembly comprising: a motor; a
