“140” refers to the motor size (frame type).
It is smaller than a 280 motor.

Typical size:

• Length: ±25–30mm

• Diameter: ±20mm

• Shaft: usually 2mm

âš¡ Electrical Specs

• Rated Voltage: 3V DC

• Speed: ±15,000 RPM (at 3V, no load)

• Low torque

• Low current draw

If you connect:

• 2 x AA batteries (3V) → normal speed

• Higher voltage than 3V → motor spins faster but may burn out

🛠 Common Uses

• Small toy cars

• Mini fans

• School projects

• Science experiments

• DIY mini tools

🚗 Is It Automotive?

No.
A 140 3V motor is not automotive because:

• Automotive systems normally use 12V or 24V

• Automotive motors are heavy-duty and sealed

• This motor is light-duty and small
