  2.  · The motor will act as a brake when stopped and can be stalled forever. I just started to use this one (from Ebay) to run a small cylindrical grinder head (for rotating the workpiece). It is hard to compare the power of stepper to AC motor. Depending on the speed it is equivalent to between 1 …

  6. Add a variable resistance in the motor circuit to reduce the voltage across the main winding if an inverter is too costly and accurate speed control is not required. The motor "slip," normally close to zero, will increase as reduced power is supplied to the motor, and the motor poles don't receive enough power to produce the force necessary to ...

  7.  · I'm trying to figure out the cheapest yet most efficient way to reduce the RPM output of my electric motor from 3480 RPM to ~60 RPM. Is this obtainable with a V-Belt pulley design? I know it's possible on paper, but would this be safe/realistic? I was also looking into worm gears, but …

  8. Im not sure, but I'd guess this has to do with some limit of the motor. Having something that spins at 500 rpm seems like it would need a gear reduction. The option of lowering the voltage to lower the speed doesn't seem like it would work, since as voltage decreases, current goes up rather quickly.

  9. how do I slow the revs on an angle grinder - for polishing, If you try to reduce the speed with some current reduction device on the grinder then the motor will not have the torque necessary to drive the polishing pad, the resistance on the motor can cause that to burn out The reduced speed of a polisher is obtained through gearing

  10.  · Hi everyone, Grinder: HeyCafe HC-600. Looks like a Mazzer. I often have to adjust my grinder since I'm in an outdoor setting. Of coourse, as is the protocol, I have to grind as I turn that collar. I wonder now if there's a way to hack the grinder so as to have an option for a lower RPM, especially when I'm only adjusting the...

  11.  · The difference in the torque of the lower rpm motor is well worth the swap in surface speed. The Craftsman took about 3-4 seconds to come up to full speed when the switch was flipped on. The big Cincy is at speed by the time the switch clicks. the 1/2hp blower fan motor on the baghouse takes longer to come up than the wheels.

  12. That doesn't imply the motor is useless, only that the grinder's belt speed will be fixed unless you add counter-shaft with sheave and a belt to adjust the belt speed. If the phases parameter is 3 or PH 3, then you will need three phase (industrial) voltage supply, a VFD or a phase converter to run the motor.

  13. The gear reduction grinders have a high-speed motor that is hooked into a set of gears that reduce the speed of the burrs. Much like the gears of a bicycle which, when going up hill are shifted down to cause the rider's legs to move quickly while the bicycle moves uphill slowly. Although these tend to be noisier than the direct drive style ...

  14.  · In short, never over-speed a grinding wheel. The speed of the grinder must be compared to the speed marked on the wheel or package to make sure the machine's speed is at or below the maximum operating speed of the wheel. Surpassing this rating risks not just wheel breakage but also the safety of shop personnel.

  15.  · The grinder with a higher turning force more easily can maintain a high speed of rotation when under load conditions. The RPM of the lower-torque grinder greatly decreases when put under load conditions. Ultimately, grinders with higher torque are able to remove more stock over a fixed period of time. Kill the Motor and the Tool Is Sure to Follow

  16. Reducing the capacitor value lowers the torque values of the torque vs. speed curve as shown below. This method of speed control is often used for fans, because the torque requirement of a fan is lower at lower speed. That means that the fan load requirement curve crosses the motor torque capability curves only at one point.

  18. The speed of an induction motor is therefore limited to a speed below synchronous speed and the difference between synchronous speed and actual speed is called slip. Example - Synchronous Speed of Electric Motor with Two Poles. A motor with two poles is supplied with power with frequency 50 Hz (1/s). The rotation speed can be calculated as

  19. A direct drive burr grinder features a low-speed motor that connects to the burrs, which allows them to spin at the same speed. The lower speed generates less, thereby preserving the quality of the beans. Direct drive burr grinders also tend to be very quiet. Q. What type of burr grinder is …

  20.  · A smaller pulley on motor, or a larger pulley on mixer will slow the speed of mixer down. If theres no one size pulley to get it to speed you want/need, then you can replace both, small drive (motor) and larger driven (mixer) pulleys to get the underdrive ratio you need

  21.  · Hi all, Im wondering what would be a (somewhat simple) way to reduce the RPM on a motor. the motor is a 1/2hp or 3/4hp, and I need to bring it down to around 500 RPM for a piece of machinery I have. If I could do this internally with the motor, great, …

  22. $begingroup$ The speed of a motor is defined by the voltage used to power it. With lower voltage, the motor has less power an less RPM. But 5-10 rpm is really low. You may want to use a small gear. $endgroup$ – Botnic Aug 14 '15 at 7:01

  24. Dont miss: Brushless DC Motor advantages and applications The Principle of Speed Control. From the above figure, the voltage equation of a simple DC motor is V = Eb + IaRa V is the supplied voltage, Eb is the back EMF, Ia is the armature current, and Ra …

  25. If the load is connected to the motor via belts, you can change the speed the load is turning by changing the pulley sizes. To get the load to slow down, increase the size of the pulley on the ...

  26. The angle grinder is an incredibly versatile tool because of the different kinds of cutting discs that can be used when working on a variety of materials. With each cutting disc and each type of material comes a new set of considerations and these have a significant influence on setting the speed of your angle grinder.
