in a dc motor, what is the meaning of continous?(current,torque,power)?

Question

Hi guys,

Ive been looking around catalogs and i know the basic definition (for a dc permanant magnet) of stall torque, no load speed. I notice that sometimes the manufacturer states the continuos current/ torque/power, what is this suppose to mean?
when trying to choose the right motor for my electric vehicle, i always look at the torque and r.p.m. at optimum power, so basically i am not sure what the manufacturer says when it comes to continuous power/current/stall torque.

Answer 1

My guess is that it's the power (etc) the motor can deliver for long periods without overheating. This would depend on its efficiency at that power and the heat-removal characteristics of its structure, fan (if any) and rated ambient conditions.

Answer 2

if your tool is running on say 110 volts and you bog it down,its still puling a 110 volts,but then the amps start going up......so maybe it means that it runs good at 110 volts but it will increase its amps to try and compensate for the load that your bearing on the tool,maybe it needs AT LEAST that many volts to run at all,
