Members zuul777 Posted January 4, 2006 Members Share Posted January 4, 2006 do u mean programming the Pic? not entirely, no. do u guys know the difference between these types of motors? I know a good bit, and morepual does too I believe, but in order to go into explinations we need to know your 1-19 scale, so that we can continue with this discussion.

Members Walters9515 Posted January 4, 2006 Author Members Share Posted January 4, 2006 Well please explain to me about them i don't know my scale i'm guessing a (2) im not really sure but lets talk about motors and the different types please Link to comment Share on other sites More sharing options...
Members MorePaul Posted January 4, 2006 Members Share Posted January 4, 2006 Originally posted by Walters9515 i don't know my scale i'm guessing a (2) im not really sure That seems reasonable for the Walters character. Would you say you, the actor portraying the character, has more knowledge? It does simplify these questions What can i do with PIC microcontroller? Probably nothing When programming it what kind of motor rotations can i get? probably none Link to comment Share on other sites More sharing options...
Members Chao Posted January 4, 2006 Members Share Posted January 4, 2006 I'm bored with this crap. Let's play the "what would Walters' productions sound like if he existed and recorded using the techniques and equipment he claimed to use?" game. My vote: An exciting mix between someone taking a long poo, your average high school garage band production, Bob Clearmountain's work, and Merzbow.

Engineering the motor control. What is programming the Pic? One has one phase. another has three times as many. another runs off DC. And instead of dC, the other runs off AC.

Members Walters9515 Posted January 5, 2006 Author Members Share Posted January 5, 2006 Most motors rotate continiously I'm trying to get different motor rotating not continiously LFO=motor LFO cycles= motor rotations A LFO can be sinewave,square wave,triangle wave, other I'm trying to make a motor rotations like a LFO cycles because a LFO is not continious it can have different shapes,slopes,curves on the output of a LFO circuit Most motors rotate continious im trying to change the shape,slope,curve of the motors rotations like a LFO LFO cycles like a motor rotations Link to comment Share on other sites More sharing options...
Members Walters9515 Posted January 5, 2006 Author Members Share Posted January 5, 2006 I want to try each one of these motors in my leslie what would be the difference between all these motors? permanent magnet dc motor? series wound? shunt wound dc motors? Brushless DC motors? brushless permanent magnet motor? permanent magnet ac motors? permanent magnet synchronous motors? Full step stepper motor? half-step stepper motor? switched reluctance motor? variable reluctance motor? AC induction motor? Universal Motor?

Members zuul777 Posted January 5, 2006 Members Share Posted January 5, 2006 LFO motors are EASY.Walters, have you ever thought about making a signature for your posts like alot of these folks do? I'd be more inclined to help if you did. Link to comment Share on other sites More sharing options...
Members Walters9515 Posted January 5, 2006 Author Members Share Posted January 5, 2006 How can i make my LFO motor what inputs would the motor need and what kind of motor would be my LFO motor? Would a Sevro motor let a LFO input waveform to control the motor? Link to comment Share on other sites More sharing options...
Members UstadKhanAli Posted January 5, 2006 Members Share Posted January 5, 2006 u shood buy a lFo motor to see how it is done and then build your own buy dewing like reverse engineering Link to comment Share on other sites More sharing options...
Members Walters9515 Posted January 5, 2006 Author Members Share Posted January 5, 2006 No one makes a LFO motor this is a very custom motor im taking about Link to comment Share on other sites More sharing options...
Members zuul777 Posted January 5, 2006 Members Share Posted January 5, 2006 He's right. LFO motors are very hard to track down. One company in norther Ireland makes these for custom applications. Prices range from us$ 500-10000 to have them make one. With a good motor shell, shaft, bearings, and bushings, one could make their own if they were half decent at motor design. Walters, how good are you at motor design? Link to comment Share on other sites More sharing options...
Members Walters9515 Posted January 5, 2006 Author Members Share Posted January 5, 2006 not good at all but i think of taking a servo motor and turning it into a LFO motor What would a LFO motor need? I need a motor with a Voltage input to control the motors spin/rotations would this be a servo motor? But Servo motors use PWM to control the motors spin/rotations Link to comment Share on other sites More sharing options...
Members MorePaul Posted January 5, 2006 Members Share Posted January 5, 2006 Originally posted by Walters9515 not good at all Ah, given this, there is a solution that may be easier for you to implement What would a LFO motor need? a motor engineer at the design helm!

Members zuul777 Posted January 5, 2006 Members Share Posted January 5, 2006 I would gut a similar sized motor and build a new one. You'll need to wind your own internal coils, so get about a mile of wire. Not sure what size you want, so I don't know what awg would be ideal.

Members zuul777 Posted January 5, 2006 Members Share Posted January 5, 2006 Walters, please tell me you know the consequences of a reversed coil. It's not something to joke about. A fellow engineer years ago blew his hand up on such a mistake. Link to comment Share on other sites More sharing options...
Members Walters9515 Posted January 5, 2006 Author Members Share Posted January 5, 2006 How can i hook up a LFO circuit to a Motor so i can speed up and down the motor with a LFO circuit? Link to comment Share on other sites More sharing options...
Members MorePaul Posted January 5, 2006 Members Share Posted January 5, 2006 AS zuul mentions, given you are at about 2 - you should consider lower-energy products for a variety of safety and practicality reasons Link to comment Share on other sites More sharing options...
Members dougb415 Posted January 5, 2006 Members Share Posted January 5, 2006 Originally posted by UstadKhanAli To my ears and powers of reasoning, the bass rotor works just as an AM device, and only for the upper two octaves or so of the bass section (200 to 800 Hz). Frequencies lower than 200 Hz are probably uneffected by a scoop of this size, since 200 Hz has a wavelength of approximately 5.5 feet. There may be some frequency-modulation effects near the 800 Hz xrossover point, but it sure sounds like AM to me. The result is a low-frequency "throb", which is very pleasant and especially powerful and beautiful when used in "slow" or "chorus" mode.by Clifford A. HenricksenCommunity Light & SoundFirst published in Recording Engineer/Producer magazine, April 1981. I bought a Motion Sound leslie "clone" that had no bass rotor; instead it used a 12" speaker that had an AM-type signal sent to it. It did NOT sound like a Leslie.

Members MorePaul Posted January 8, 2006 Members Share Posted January 8, 2006 There's certainly a lot to "the leslie sound" and there's a lot of varying expectations (one thing to consider, for instance, is do we simply mean "rotating speaker" or do we mean the tone of the cabinet, the sound of the amplifier, etc) but within the rotor, yeah, 200-800hz holds a lot of info and one thing I find sims in general lack is the "lighthouse effect" -- wherein what you are hearing in a room is not just a modulation in a direct sound...but a shifting of reflected sound...you're, in effect, altering the room.
