Will this motor work with an AC router speed controller? I'd like to use it on a homemade lathe but I've got to have some means of controlling RPM.

I would not recommend using an AC router speed controller. I have a controller like this, and it works fine on my router, but you don't want to starve a big motor like the Grizzley G2905. Your best bet is to get two 4-step pulleys with 5/8" bore, the sort of setup I see on my Sears bench drill. The motor would best be mounted on a hinged baseplate that has some kind of spring tensioner. It would only take a few seconds to move the drive belt from a higher ratio pair of pulley grooves to a lower one, and vice versa. Your slowest speed (and most power) sees the belt in the smallest pulley segment at the motor end, and the biggest segment at the machine end, which you probably already know.

I would use a Variable Frequency Drive (VFD) instead... to regulate the rpm of the motor. Here is an excellent video detailing what you need to do install/setup a VFD to an AC Motor: https://www.youtube.com/watch?v=23lwqq9uGg4

Like others have stated, my Makita has a single speed of 10,000 rpm. I suspect that the "Product Description" is for a different tool. The "From the Manufacturer" description appears to be correct. That said, I think it's still a great tool and would buy it again.

Yes, it can do variable speed. It's a brushed DC motor, so varying the current will vary the speed, & reversing the polarity will reverse the direction of rotation. One can use a traditional analog current controller, or a PWM current controller, which will be more efficient. - bc for AnaV

Hi Taryn, I'm sorry to say I can't help you here, I used the motor to turn a grain mill using a 11/2 inch pully on the motor and a 14" pully on the mill to reduce the RPMs from 1,725 to 90, I use it to grind grain to make beer. It worked just fine.

Yes you can use a speed controller on this blower motor. Use one that is rated for atleast two amps or greater. Do not use a dimmer switch designed for incandescent lighting.

I don't think that the 9rpm setup will do it. I tried using the 9 rpm setup geared down and then further reduced with a belt drive to power a set of small backyard windmill blades on a bearing setup, but the motor fried on the first try.

This motor is designed for industrial sewing machines which have a treddle/pedal to control the speed. It is wired for 120 Volt AC current. Don't try to use this on any other sewing machine unless it's an industrial heavy duty with a table and pedal.

No, it has no speed control built into it. I haven't added any control to the fans that I run, I figure one more thing to break. I do have a control on a shop vac that works well that is made by VenTech, sold by Amazon believe it or not. It is rated for the amperage you are dealing with and it works very well. I would consider it, but there are very many options. Hope this helps. Dan

The only one I know about was an easy solid state construction project way back in the '90s. It had only a handful of components, including a triac, a silicone controlled rectifier (SCR), a potentiometer (variable resistor) and about 6 resistors and capacitors. It was in a book of simple electronic projects. I built it in an hour (once I had the parts). Unfortunately, I lent it to someone who tried to use it with a 5HP elevator motor. That slagged it. The other responder to your original question is WRONG. Any speed controller that reduced voltage, also reduces available torque. That'll work for a fan because the load is small & balanced. That isn't very desirable in a lathe motor as it will stall the machine if anything but the smallest cuts are attempted. The solid state controllers such as the one sold by Amazon interrupts the AC waveform to a greater or lesser extent, thereby allowing full torque at any speed (& smooth operation at even slow speeds). I'd Google "solid state AC motor speed controller", sift the hits for any mention of "DC" - which would rule it out for your application. Check out what's left for your motor (check with the seller as you did with Amazon). BTW, the reason your lathe has gears (or pulleys) to regulate speed is because, until Triacs, there was no other way to slow an AC motor & retain necessary torque. Good luck.

Yes, I would say horsepower matters, but this is related to the amperage. I use this speed control on a router that is also 15 amps and it works great. I'm not sure why you would want to change the speed of a power miter saw, but this unit should work fine.

This is a speed control, rated for 50 amps MAX. You do not control amps, you just must make sure you use a motor rated for 50 amps or less

NO. I even went so far as to try one for brushless motors (even though I was nearly positive it was a standard brush- style). Speed controllers do NOT work with this fan.

Yes, it is variable. You should buy a PMW controler to vary the speed. But be careful if you need to reverse the motor with a polarity reversing toggle switch. Put the motor leads on the toggle switch, not the power leads.

Bosch specifically states in the documentation that it "is designed only for use with Bosch 1617/18 Series router motors.". I would be doubtful, unless I could get my hands on a Bosch router base for a test fit and confirm otherwise.

Hmm.. I would have said no due to the size of the motor but if you search Amazon for fan speed controller they have at least one that will handle up to 15 amps

According to the description on the router speed control it only works on motors with brushes i.e. router,drill,but not any induction motors.

I would suspect the Bosch router base is a dedicated affair, with their router motor having posts that slide into slots on their router base. I doubt the Porter Cable motor would interface.
