I want to make my ryobi 16 in scroll saw to a variable speed unit but the motor must be the brush type so i need to know if it does have brushes


more than likely but if it doesn't consider this
the ceiling fan is a brushless motor and its speed is controlled by a variable rheostat and there are plenty of ac motors that are speed controlled by clipping the sine wave of the ac current that are not brush and armature motors
Talk with an accredited electrician as to electric speed controls for the types of motors

Want to replace with either a two speed or variable speed motor, and suggestions?


You will need to install a special controller if you change to a 2 speed. Because there will be an additional wire (4 wires vs. 3) with a 2nd speed to operate.
If you go with a variable speed motor, then again, a special controller will be required to utilize a reo-stat type of switch with will allow a selection of slowly increasing voltage to motor which will in turn allow the motor to spin quicker.

Instead of the hassle above, just go with a "One deal package" all nicely bundled ready for installation. It has it all within it - What...? A variable speed complete pump! That will be the sweetest thing for you if you are looking to go that route!

How to wiring the power cord to the F/R switch?


Will need more information: make, model, etc. A corded drill motor can be AC or DC. It can be variable speed on not. An AC motor can be reversed by changing the magnetic polarity of the start winding (switching the two start winding wires). This type of wiring in not usually variable speed. A DC motor is reversed by changing the electrical polarity of the primary motor leads. Usually these type of devices have a rectifier circuit to produce DC voltage and use a PWM signal to develop variable speed.

The blower doesn't work for the a/c


Check fuses, then the relay. Fused power to the lower speeds, and a relay sends power to the fan for high speed. Some cars have an electronic blower motor for a variable speed system. The motor could be bad, or the motor board could be bad, if you have a variable speed blower motor. Very expensive to replace. 250 to 400 dollars. good luck.

I have a E2EB-017HA air handler and I want to change it to a variable speed motor. Is this possible


Some companies do sell a variable speed kit. It includes the motor and controls. Get your model and serial number of your unit and contact your local Payne dealer. The can locate the proper kit if available for you.

Spin half the speed


Hi.

Depending on the make and model, and type of washer, you may need to test and eventually replace the following parts:


On top loads:


Variable speed motor .
Motor coupler.
Transmission.
Control board.
Motor control unit (if present)


On front load :


Variable speed motor .
Motor coupler.
Control board.
Motor control unit.


On top load the problem is often transmission or variable speed motor. On front load MCU or motor.

Generally going to have to be addressing the drive motor, either substituting a lower speed clutch motor for the existing one, ie if you have 3000 rpm motor, then going to a 1725 rpm motor. Alternatively, selling the clutch motor and buying a servo motor instead, which should be available with a variable maximum speed control. The Sewquiet 4000 can select different speed ranges with the flick of a switch. If you already have a servo motor and it does not have a variable max speed, then switching the drive pulley on the servo motor to a smaller size should help
A more convoluted solution would be building a support under the table for a layshaft with different pulley sizes so that the motor could drive one pulley and then a smaller pulley on the shaft would drive the sewing machine. Not a bolt on solution but pretty cheap to do if you are good at fabricating.
