Converting an electrical appliance with DC motor to AC watts

Click For Summary

Discussion Overview

The discussion revolves around comparing the power of two electrical appliances: one with a DC motor and the other with an AC motor. Participants explore the implications of wattage ratings and the nature of the motors in terms of their power output and efficiency.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant compares a 250W AC appliance with a 72W DC appliance, seeking to determine which has a more powerful motor.
  • Another participant argues that the question cannot be answered without additional context about the appliances, citing examples of different appliances with varying power consumption and motor capabilities.
  • Clarification is provided that the DC appliance in question is an electric hand mixer.
  • There is a discussion about whether wattage differences between AC and DC motors affect their power output, with one participant asserting that "watts is watts" and suggesting that the type of current does not matter.
  • Concerns are raised about the practicality of a 120V DC kitchen appliance, with skepticism expressed regarding its feasibility.
  • A participant questions how AC is converted to DC in the context of the blender, indicating a need for further exploration of the topic.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the implications of wattage differences between AC and DC motors, and multiple competing views remain regarding the power comparison and the nature of the appliances.

Contextual Notes

There are unresolved assumptions regarding the specific applications and operational characteristics of the appliances being compared, as well as the conversion processes between AC and DC.

Hi,

I'm comparing two electrical appliances, one with a DC motor and the other with an AC motor. The AC appliance has 250 watts. The DC appliance has 0.6 amps and 120 volts, and its wattage is 72. Given these specs, I would like to know which appliance would have a more powerful motor?

In addition, what would be the AC watt equivalent of a DC motor with the above specs?

That cannot possibly be answered without knowing more about the appliance. For instance, my dishwasher has a much more powerful motor than my electric range, yet the range consumes much more power. For those of you who think the range has no motor, you are forgetting about the clock. :)
 
The appliance is an electric hand mixer.

Just to be clear, you're asking which of a 250W hand-blender or a 72W hand-blender is the more powerful?
 
Yes, because the 72 watt one is a DC motor with the above specs and the 250 watt one is an AC motor. Although one obviously has a higher wattage, I'm asking if it makes a difference whether a motor is a DC or AC.
 
Watts is watts. It does not make a difference if they are AC or DC.

Still...a 120V DC kitchen appliance? Doubt it.

Your question is kinda odd...
Let's start with a question for you:

How is AC converted to DC...in your blender for example.
