does the variable power knob instantaneously control the motor speed or is there a lag?

The blender follows the laws of physics - so of course there's a lag, caused by inertia. However this doesn't seem to be much of an issue.

Mine is a 371 and is not variable speed. If I remember correctly when I bought mine there was another model that was variable speed. Maybe it was the 371K. Anyway the thing gets hot with continued use. "Continued" meaning 3 minutes or so. Good luck!

Greetings: I will give you a qualified yes on the variable speeds. THe motor is a standard brushed DC motor, so load and drive voltage affect speed. You can vary the speed by either varying the drive voltage, or, as in current automobiles, with a pulse-width modulated source. Hope this helps! Terry S.

No, It has no dedicated variable speed control. It does ramp up the speed gradually as you pull in the trigger, which is a nice feature, as it allows you to start a cut slowly without having the blade jump out of the material.

We did. We did not use a variable speed controller though. We set the fans to a high speed and then replaced the control with a simple on/off switch.

No, I actually came across doing this and a these "speed controller" control current where as a variac (which controls voltage) is what you need to control heat. I wound up using my router speed controller for a shop fan. And got a variac for my heater.

A two speed control works, but a variable speed control does not. I tried a variable control with no luck.

It's only on or off , no variable controls . It's worked as well as the mikita and dewalt grinders I've owned for about 35% of the price I typically paid .

Agree with previous responder. Off then slide the switch to the variable speed you need. Then slide switch to off when done.

This control will not work with slow statting motor! I believe my answer is no.

I am fairly certain that the speed is adjustable but 2 hospitalizations have prevented me fro, using it. I recall a speed adjustment knob on it.

Definitely variable. Think of the speeds as gearing. Within that gearing you can control how fast or slow based on pull of the trigger from min to max allowed by that gearing.

No measurable lag. But it's not like an analog speed control - it's either on or off. But I can still move to where I want, even at 30x zoom.

This is an accessory plug-in speed control unit. I've only used it on small rotating motor type things. It slows them down by adjusting the power. The motor still seems to have been fine just not as fast when the unit is adjusted. I guess I don't really understand the question, what kind of power tool would need to be slowed down while maintaining full power?

I use mine on a bobbin winder that is only one speed--fast. I needed to slow it down. This pedal makes it a variable speed.

The answer is, I don't know. This control performs differently with different tools, appliances, etc. It must depend on the type of inner electrical control of each tool, appliance, etc. I bought one to control the speed of a fan but it did not perform, it was either on or off even in the variable mode. I would go to the local electrical parts store and ask some questions before ordering.

No variable speed on the small 18 volt I don't think any band is variable because of blade stall
