How do i choose the right ac or dc motor

[slee95]

I'm building a wire strippers by cutting a hole in a piece of 2x4 which has a blade on the bottom of the hole. I want to use a motor to pull the wire threw by using a motor a gear and a strip of metal. The strip of metal clamps the wire down on the gear which is turned by the motor. I was wondering what type of motor do i want to use to pull the wire threw? I was thinking of using a ace 120v ac vacuum motor but don't know if it is the correct type of motor to use.

Think about the speed (in meters per second) you want the wire to got at. Divide that by the circumference of the gear (in meters) and multiply by 60. The answer is the rpm you need. Look up the RPM in the spec for the motor.

Measure the force (in Newtons) required to pull the wire through at that speed. Multiply by the radius of the gear (in meters) to get the Torque (in Newton Meters). Check the RPM vs Torque curve on the motor spec to confirm the RPM is still ok at that torque.

Multiply the RPM by 0.105 to get the angular velocity (in Radians per Second). Multiply that by the torque to get the power needed in Watts. Look that up on the motor spec.

I suspect many motors will go too fast for what you want.

If you are trying to reclaim the copper from scrap wire then I think most people burn it off :-(

Can't burn it off because i live in town. It is bad for the ozone and if caught doing so you will be charged a good size fine for doing so.I have been told that you will be docked you if you scorch the wire.

When choosing a motor for your wire stripper, there are a few factors to consider. The first is the type of power source, AC or DC. AC motors are typically used for high power applications, while DC motors are better for low power applications. Since you are building a wire stripper, it is likely that you will need a motor with high power, so an AC motor may be a better choice.

Next, you will want to consider the speed and torque of the motor. The speed of the motor will determine how fast it can pull the wire through, while the torque will determine how much force it can apply to the wire. You will want to choose a motor with a high enough speed and torque to effectively pull the wire through without getting stuck or causing damage.

In terms of specific motor types, there are a few options that could work for your wire stripper. One option is a universal motor, which can operate on both AC and DC power and can provide high speeds and torque. Another option is a brushed DC motor, which is known for its efficiency and ability to provide high torque. You could also consider a stepper motor, which is commonly used in precision applications and can provide precise control over speed and position.

In terms of the specific motor you mentioned, the Ace 120v AC vacuum motor, it may not be the best choice for your wire stripper. Vacuum motors are typically used for suction or blowing applications, and may not have the necessary speed and torque for pulling wire. It's best to research the specifications of the motor and compare them to your requirements before making a decision.

Overall, the key factors to consider when choosing a motor for your wire stripper are power source, speed, and torque. It may also be helpful to consult with a motor expert or do further research to determine the best motor for your specific application.
