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.

The vector from the origin to the point A is given as (6,−2,−4), and the unit
vector directed from the origin toward point B is (2,−2, 1)/3. If points A and
B are ten units apart, find the coordinates of point B.

Many processes, such as design, are non-deterministic. When you make a schedule for a project, you estimate how long each task will take. In design, if you are trying to come up with something that has never been done before, you don't know how long each task will take. How do you manage the schedule? For example, produce a schedule for replacing coal fired power plants with fusion power plants.

hi

i want to design piston pump my flow rate is 2.6 GPM,AND my fluid is water. my problem is in getting the number of diameter and the lenght of piston rod and i also i want to use cam what should be the diameter of the cam ,and for getting the differantial pressure in the pump or cyliner we should have the speed of piston how do we get this value.? i just want to use one piston or plunger, i have got the bore or diameter of piston and stroke and i know the range of my rpm,and also i just want to use one cam not crank shaft to change rotating movement to linear movement. please tell me the proper formula for my question or give me useful web site relevant to my question?

best regards
