How to Adapt Existing Motors to Power New Equipment
A mechanical adapter system that lets you connect an existing motor's spinning shaft to a new, secondary machine like a generator or pump.
Original patent title: “Accessory rotary drive system and method”
A mechanical adapter system that lets you connect an existing motor's spinning shaft to a new, secondary machine like a generator or pump. Granted to TSI Products Inc in 2025 with 11 claims.
Key facts
Coverage
What does this patent actually cover?
This system acts as a bridge between an existing rotary motor and a new piece of equipment that needs power. It uses a central hub that fits over the motor's original stem, transferring that rotation into a new drive shaft. This shaft is supported by a housing and extends to a drive wheel, such as a pulley, which then uses a belt to spin the secondary component. This allows an existing motor to do extra work, such as driving a condenser, alternator, or hydraulic pump, without needing a completely new motor.
The gap
What does this patent NOT cover?
- Does not cover the original motor or the secondary component being driven.
- Does not cover systems that use direct gear-to-gear coupling without a drive shaft.
- Does not cover internal combustion engines or electric motors themselves.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
What made this novel
The system uses a conical shaft section combined with a keyed channel to ensure the drive wheel stays locked to the shaft even under high torque, preventing slippage during power transfer.

Why it matters
The bigger picture
In industrial and mechanical settings, replacing an entire motor system is expensive and time-consuming. This patent provides a modular way to expand the utility of existing machinery by piggybacking off an existing power source, which is critical for retrofitting older equipment with modern accessories.
