In summary, the conversation revolved around the speaker's project of creating a toy car operated by a remote control. They were having trouble finding suitable motors that would generate low RPMs, as well as having gears or wheels to attach to the car. The speaker requested for recommendations of 1-9V motors with these specifications. A resource was provided for assistance.

Hey guys,

I am working on a toy car which is operated with a remote control (either on or off, very simple). My problem is that the motors I have (some 9V, 7.5V, and 1.5-3V) all seem to either stall or go waaaay too fast. Not to mention that neither of them have gears or wheels (I ended up soldering the end of the motors to a ball of solder implanted in plastic pine-wood derby wheels). I was wondering if anyone knew of some 1-9V motors that would generate low RPM's (enough to make a small car move ~.3 m/s), preferably with either gears, wheels, or something to attach wheels.

Thanks a lot,

John

FAQ: Motor for Toy Car: Finding the Right RPM

What is the purpose of a motor in a toy car?

The motor in a toy car is responsible for converting electrical energy into mechanical energy, which powers the movement of the car's wheels. It is an essential component that allows the car to move and perform various functions.

What is RPM and why is it important when choosing a motor for a toy car?

RPM stands for revolutions per minute and refers to the number of rotations the motor can make in one minute. It is important when choosing a motor for a toy car because it determines the speed and torque of the car. A higher RPM motor will result in a faster car, while a lower RPM motor will provide more torque for uphill or off-road driving.

How do I determine the right RPM for a motor in a toy car?

The right RPM for a motor in a toy car depends on the size and weight of the car, as well as the intended use. Generally, a motor with an RPM of 5000-6000 is suitable for a small toy car, while larger cars may require a motor with a higher RPM. It is best to consult the manufacturer's recommendations or do some experimentation to find the ideal RPM for your specific toy car.

What are the different types of motors available for toy cars?

There are various types of motors available for toy cars, including brushed DC motors, brushless DC motors, and servo motors. Brushed DC motors are the most common and affordable option, while brushless DC motors offer higher RPM and efficiency. Servo motors are often used for steering and provide precise control over the car's movements.

Can I change the RPM of a motor in a toy car?

In most cases, the RPM of a motor in a toy car cannot be changed. However, you can adjust the overall speed and torque of the car by changing the gear ratio or using a different power source. Some high-end motors may have adjustable RPM settings, but these are not typically found in toy cars.
