Metal body · 130 size, 3–6 VShaft (Ø 2 mm)Nylon back coverSolder terminals (+ / −)

Metal cylindrical body, thin shaft on the front, two solder terminals at the back
130 type: body ≈ 20 × 15 × 25 mm, shaft diameter 2 mm

Outputs

DC motor

In simple terms

What is this?

A shaft that turns with electricity; a small spinner that speeds up as you raise the voltage.

What is it for?

Spins a fan, wheel or pump; reversing its leads makes it spin the other way.

Where do you see it?

Toy cars, hair dryers and electric shavers.

How do you spot it?

A cylindrical metal body with a rotating shaft at one end and two solder tabs at the back.

Caution:

Draws a lot of current at start-up; don't drive it directly from a pin and don't hold the spinning shaft.

Technical definition

It is a brushed motor that spins when DC voltage is applied. Reversing the leads reverses the direction, and lowering the voltage lowers the speed. While running, especially at start-up, it draws more current than a pin can supply.

Features typical

Voltage: 3–6 V (130 type)
Inrush current: A few times the operating current
Direction: Turns the other way when the terminals are swapped
Speed control: With PWM
Driving: Transistor or MOSFET; H-bridge for direction
Example part: 130-type toy motor (3–6 V)

Common mistakes

Driving directly from a pinA motor draws hundreds of mA and produces electrical noise. Drive it with a MOSFET or transistor.

Forgetting the flyback diodeA motor is a coil; when it switches off it produces a reverse spike. Put a reverse-parallel diode across the motor’s terminals.

Running it from a 9 V batteryA 9 V battery can't supply the motor current and runs out quickly. Use an AA battery pack or Li-ion.
