RPM of his 12V, 066A D.C motor from 60 to 30. He wonders if he can control the speed by controlling the volts supplied, but that depends on the nature of the motor. If that is not possible, he could use gears. Another option is to use PWM on the 12V supply, as it will still provide good torque at half-speed. Some good examples of PWM controllers can be found on eBay. In summary, Dave can either control the voltage or use gearing or PWM to successfully reduce the RPM of his motor.

I have a 12V, 066A D.C motor, and 60 RPM. Want to reduce the RPM (60 to 30.
What should I need to do?

The electric motor may, or may not, allow you to control the speed by controlling the volts supplied. Some motors allow this, some do not. You will have to investigate the nature of your electric motor to determine this. Then if the motor does allow this, can you supply different voltages?

If not, then could you use gears?

If he still wants good torque at half-speed, he would need to use PWM on his 12V supply, no?

yup, that or gearing will be the 2 successful ways

here's some good examples from eBay ...

What are the steps to reduce the RPM of a 12V 0.66A D.C motor from 60 to 30?

The following steps can be taken to reduce the RPM of a 12V 0.66A D.C motor from 60 to 30:

  1. Identify the type of motor and its specifications
  2. Adjust the voltage input to the motor
  3. Change the gear ratio
  4. Install a variable speed drive or controller
  5. Modify the motor's physical components such as the size of the rotor or stator

Can the RPM of a D.C motor be reduced without changing the voltage input?

Yes, the RPM of a D.C motor can be reduced without changing the voltage input by changing the gear ratio, installing a variable speed drive or controller, or modifying the motor's physical components.

What are some factors to consider when reducing the RPM of a D.C motor?

Some factors to consider when reducing the RPM of a D.C motor include the type and specifications of the motor, the desired RPM, the intended use of the motor, and the available resources for modifications.

Is it possible to reduce the RPM of a D.C motor beyond 30?

Yes, it is possible to reduce the RPM of a D.C motor beyond 30 by implementing additional modifications such as changing the gear ratio or installing a different motor controller.

Can I reduce the RPM of a D.C motor without any modifications?

No, reducing the RPM of a D.C motor typically requires some modifications to the motor or its operating conditions. Simply changing the voltage input may not be enough to achieve the desired RPM reduction.
