Where to Buy 24VDC Electric Motor up to 500 kg Load, 180 RPM, 1000Nm Torque

Click For Summary

Discussion Overview

The discussion revolves around sourcing a 24VDC electric motor capable of handling a load of up to 500 kg, with specifications including a maximum speed of 180 rpm and a torque of 1000Nm. The conversation touches on potential applications and alternatives for such motors.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant inquires about the availability of a 24VDC electric motor with specific load and performance requirements.
  • Another participant suggests approaching manufacturers of golf carts, noting that while they typically use 48 volts, lighter options may exist. They also mention the possibility of using aircraft servo mechanisms that operate at 24 volts.
  • A different participant points out that the requested specifications would require an 18,000 watt (25 HP) motor, which they claim would draw 750 amps, suggesting that such a motor in 24 volts is unlikely to be found.
  • Another reply proposes that using a 240 VDC motor might be feasible, although it would necessitate accounting for losses, and references a source for a 25 HP motor that operates at 400 rpm.
  • This participant also mentions that electric car motors can provide peak values of 18KW.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of sourcing a 24VDC motor with the specified capabilities, with some suggesting alternatives and others questioning the practicality of the request. No consensus is reached regarding the best approach or solution.

Contextual Notes

The discussion highlights the challenges of finding a motor that meets the specified requirements, including potential limitations related to voltage and current ratings. There are unresolved considerations regarding the efficiency and performance of suggested alternatives.

Anyone know where will i be able to get a 24VDC Electric Motor [with or with gear reduction] that can take up to a maximum of 500 kg load at a maximum of 180 rpm at a maximum torque of 1000Nm?

Appreciate that someone can help.
Thank you.

My first thought would be to approach a manufacturer of golf carts. I think that they're normally 48-volt, but there might be lighter ones available. You could also investigate aircraft servo mechanisms, many of which are 24-volt.

You are asking for an 18,000 watt [25 HP] motor. That is a 750 Amp motor! You aren't going to find that in 24 volts [at least, not that I've ever seen].

Normally we would use a 480 VAC 3 phase motor for an application like this.
 
It looks like you might be able to do this using 240 VDC, but you would still have to allow for losses.

You can get 18KW peak values from electric car motors.
