 · An Uno should be fine. Can you control the RPM of a stepper motor with a POT and the arduino UNO analog ( i assume the analog because the pwm pins are being used to drive the motor) or would this need to be worked out within the code timing ( reading the input from the POT when the motor is not "stepping") Yes you should be easily able to …

 · Horse power is a measure of work not torque! and torque is what keeps you from bogging a motor. Horse power is a calculation of how much work can be done in a given amount of time. This means that a 3600 RPM motor Rated at 1 HP will have less torque (incorrectly referred to as power) available then a 1 HP motor rated at 1800 RPM.

 · Before connecting the block to the angle grinder, check it. Take a plug-in electrical outlet. Insert 2 wires into it, one of which connect to the board, and the other to the network cable. Connect another wire to the network board. As you can see, the regulator is connected in series in the electrical circuit.

 · The Perfect Motor RPM and Drive Wheel Combo This is what Wikipedia has to say about Surface Speed Per Minute – SFM the industry standard is defined as the number of linear feet that a location on a rotating component travels in one minute. Its most common use is in the measurement of cutting speed (surface speed) in machining.

 · To balance the resultant effect, the reduced-diameter wheel should be operated at a higher rpm, when available on the grinder. Two important rules must, however, be observed: (a) In no case must the wheel surface speed in fpm be raised above the peripheral speed of a new wheel when operated at the prescribed rpm.
