Multiple electric motors on a single shaft

An electric motor comprising:

• a motor housing;
• a shaft that extends in a longitudinal direction through a length of the motor housing;
• a first motor disposed within the motor housing and mounted to the shaft;
• a second motor disposed within the motor housing and mounted to the shaft;
• an adaptor disposed within the motor housing, wherein the adaptor supports and pilots the first motor and the second motor;
• a first motor controller disposed on the adaptor and within the motor housing, the first motor controller electrically connected to the first motor and programmed in a speed control mode to rotate the first motor at an input speed;
• and
• a second motor controller disposed on the adaptor and within the motor housing, the second motor controller electrically connected to the second motor and programmed in a speed control mode to rotate the second motor at less than the input speed.

An electric motor comprising:

• a motor housing;
• a shaft that extends in a longitudinal direction through a length of the motor housing;
• a first motor disposed within the motor housing and mounted to the shaft;
• a second motor disposed within the motor housing and mounted to the shaft;
• an adaptor disposed within the motor housing, wherein a portion of the first motor and a portion of the second motor are disposed within the adaptor and the adaptor supports and pilots the first motor and the second motor;
• at least one motor controller disposed on the adaptor and within the motor housing, the at least one motor controller electrically connected to the first motor and to the second motor;
• a fan coupled to the shaft within the motor housing, the fan external to the first motor and the second motor;
• and
• a baffle disposed within the motor housing and around the shaft external to the first motor and the second motor, the baffle having a conical shape and being disposed adjacent the fan, wherein the adaptor include a series of fins that extend radially outward and longitudinally along a direction of the shaft.
