New 3Pcs Small DC Motor 3 to 5V DIY Toy 130 Miniature Electric Motor Low Voltage

New 3Pcs Small DC Motor 3 to 5V DIY Toy 130 Miniature Electric Motor Low Voltage Small DC motor 3 to 5V Runs on as little as 3 Volts, 5 Volts Maximum. Current at 5V: 400 mA No Load, 1.7A Stalled (Do not stall for more than a few seconds at 5V). The RoboRED, when running from an external power supply, can supply 5V at 2A which can run one of these motors. Otherwise a separate 5V supply is needed. Runs well from two AA batteries. Can be speed controlled with PWM (Pulse Width Modulation) by for Arduino. A power transistor must be used to control the motor; for Arduino pins do not have enough power to run this motor directly. Size: 20 * 15 * 25 Shaft length: 8mm Shaft Diameter: 2mm Voltage: 1-6v Reference current: 0.35-0.4A 3v speed: 17000-18000 rpm
