Stacked Motor Drive Assembly for High Power in Tight Spaces

The patent divides a single large motor into multiple smaller motors (first motor and second motor) that are stacked vertically. Each motor has its own rotor and stator assembly, and they work together to provide the total required power output. This segmentation allows the system to achieve significant power while maintaining a compact footprint, as the combined volume of multiple small motors is less than a single large motor providing equivalent power.

The patent transitions from a horizontal arrangement of motor components to a vertical stacking configuration. The first and second motors are arranged vertically with their rotors stacked along the vertical axis, and the drive belt wraps around both rotors in a vertical plane. This dimensional change allows efficient use of vertical space while maintaining compact horizontal footprint, resolving the contradiction between power output and device volume.

The patent segments the power generation function into multiple smaller motors, each with standard化的 components (stators, rotors, windings). These modular units can be manufactured using standard production processes and then assembled together, reducing tooling costs and enabling economies of scale. The segmented approach allows for easier manufacturing and lower overall cost compared to producing a single custom large motor.

The patent changes the operational parameters by using multiple motors operating in parallel rather than one motor. Each motor operates at optimized parameters for its size, and their combined output achieves the required total power. This parameter change enables the use of smaller, more efficient motors that can be manufactured more cost-effectively while meeting the overall power requirements.
