I have an application coming up that will require me to run a 1/4 hand drill at a specific (yet adjustable) speed. The drill is rated at 6 amps. That is far more than my normal motors of 3x that size use. Do you think that a GS1-10P5 (2.5A rating) would be sufficient. I suspect that the 6 amp rating on the drill is at a complete stall & my application will never reach that point (hopefully). Any ideas? Or is the GS1 even going in the right direction on this project? Should I try something else?

Thanks in advance,

newvegas,

I'm going out on a limb here, My guess the drill motor is a 120 volt universal motor. With this type of motor the voltage will vary the speed. a better match for the motor would be somthing like a grainger # 4x797. If the drill motor is not this type then something else may be more suitable. Speed control with a universal type motor is inherently bad, typicaly 50% speed change between full load and no load. The output of the GS1-10p5 is limited to 2.5 amps continious and 3.75 amps intermittant for one minute. Would this be enough? Only you would know, we cannot tell from the information supplied with the original post. One other thing that might be an issue would be the drive will put out 240 volts. It is possible to limit this with programming to 120 volts. Overall I would not recomend you use the GS1-10p5 with a universal type motor.
