cheap speed controller for a treadmill motor

Dear sir can i buy from u dc motor controller ? Pinout matching of the two ICs is not important, you just have to use the 4049 gates in the appropriate locations as indicated in the diagram, you can refer to the datasheet of the 4049 IC for learning the details. MC2100LT 12 Treadmill Motor Speed Control GoldsGym ProForm Sears 266118 264597. Is that not the case? Thanks Mah, you are right with your assumptions, however converting 220V AC to DC will result in 310 V, which can damage the motor. $179.95. $8.70 shipping. Next, replace C3 with 100uF/25V And replace the 1k at pin5 of IC2 with a 1k pot. which schematic sir,i am still confuagused? And how about a buck converter with flywheel circuit, just like in the link below? i'll try to update the info in the diagram soon…. Mr.Majumdar as you said at the begining "Here's a SIMPLE PWM based motor speed controller circuit which can be used for controlling a treadmill speed right from zero to maximum." I suggested an SMPS since most smps have regulated output using zener controlled feedback. The circuit also provides an instant bidirectional stop and reversal of the motor rotation by a single flick of a given switch. Also I’ve used 1N4744 as a D1.What do you think Sir. After closer examination it looks like BJTs were wrongly configured. Technical Repair: 3: Aug 5, 2020: J: Speed Control Board for Treadmill Motor on a Belt Grinder Build: Technical Repair: 6: Apr 17, 2020: P: Treadmill Motor Speed Controller: Technical Repair: 15: Aug 2, 2019: Treadmill motor speed control: Technical Repair: 12: Dec 17, 2018 Im not sure how crucial smps was to the operation of the circuit. . A wide variety of treadmill motor controller board options are available to you, such as dc motor. Alright, let it be so, let's forget about this . I ran my motor on a paid 4kw dimmer with 8A bridge rectifier. I have another question – what will happend if the value of the pot increases rapidly when the engine goes at slow speed? How about 2 or even 3 ST901T's in parallel? …please make sure the negative of 110V DC joins with the 12v negative of the circuit…. This level is directly translated through optimized PWMs at pin#3 of the same IC as explained above. Anyway . But when i start the circuit at zero, i can turn it slowly to max but it won't turn down anymore. The parameters are:– 220V AC power grid– 180V permanent magnet DC motor 7Amps motor– main control element a SCR (thyristor) simultaneously acting like rectifier and control element with phase controlling circuit– a capacitor in parallel after the thyristor acting simultaneously like smoothing element for the phase-cutted sine and voltage-raising capacitor (just like in the last circuit you offered me).– a SCR control circuit that uses phase-cut method – cutting the sine at different angles in order to get different voltage values above the motor. It appears that the load receives full tension very quickly. Thanks again. As in the circuit above, a bridge rectifier and a smoothing capacitor should give my treadmill DC motor what it needs . The speed cannot be adjusted from zero (at least not in my case) and is unstable. I used a light bulb as a load, because the motor is a very risky try. ?thank you, please do exactly as shown in the first diagram, you will succeed in getting the intended results.

A perfect smooth driving is not really necessary to me, it is used to drive a diy small flour mill. Check the specs to be sure they’re compatible with your motor. No, triacs cannot be added in parallel, because they have different working characteristics compared to transistors. Are 100V enough for Q1 in my case?How about C3 (the reservoir capacitor) from the link? It has a red & black wire, plus 2 blue wires. I have a problem on the kind of project, i would really appreciate any assistance. Hello Swagatam, thanks for all the information you give us. I am also the founder of the website: https://www.homemade-circuits.com/, where I love sharing my innovative circuit ideas and tutorials. hello, I made the second circuit replacing the mosfet for irfp460 to run a 180v treadmill motor, the problem is that the mosfet overheats and the motor shuts down, what would be the problem? So you will have to attach a large heatsink to the mosfet to control its heating, or add two mosfets in parallel, or use a 300 V 70 amp mosfet or similar which may have a much lower RDson resistance. Hello Njabulo, you can use the H-bridge section from the above design and use it with your Arduino, a pair of anti-phase signals will be required for triggering the bJT H-bridge and the PWM could be injected at the bases of the low side BJTs. OK, how about if I use FJL6920 with TIP29C as the NPN darlington? Dear Linus, It seems the sensor system is installed to control the motor over-speed through feedback…so may be the feedback loop has some problems and it could ne latching ON and stopping the motor from rotating. please advise if there is anything else in the auto door control circuit I must change for it to work with my 250w 110v dc motor. the dimmer chopper circuit above can be used as is it, or some components should be changed. Hi Kakooza, if it's a DC motor then you can definitely use the first design which is explained in the above article. If you want the H bridge, then Darlington may not be required. Model #DC-92U. alright I appreciate your help. . Hi, mr.Majumdar, I did the first circuit.

Whether you’re looking to purchase a new treadmill or looking to update an existing one, knowing about which kind of motor to look for is vital to the success of your treadmill use. This motor is a beast Swag, I have never seen such a large treadmill motor!!! Free shipping. yes 13/14V will cause no harm to the circuit although a fixed 12V is the recommended value….initially you can go ahead with your available set up, and see how it responds. I really don’t know if that is possible and even more I don’t know how to handle the high starting current of the motor. I think it will be much more comfortable for the motor starting at 20-30rpm or even less, for example instead of, let's say, 300rpm. Your work will be highly appreciated because I'm trying to run this treadmill for 4 months. Required fields are marked *. Thanks again! Thanks for the great design! Maybe u can try. https://www.homemade-circuits.com/wp-content/uploads/2020/02/treadmill-motor-speed-controller-circuit.jpg. A bad solder won't cause a burning problem according to me, I think the treadmill motor could have exceeded the max amp rating of the BJTs. By the way the author of the circuit I uploaded says that the C1 capacitor's value is determined experimentally (between 1 and 10 uF) to choose less jerk and max torque (something like compromise between both). I thought the thyristor will work like half-wave rectifier together with the phase cut-off process. Thanks its very usfel article but why you are not use isolate circuit between high and low voltage like using a photocoubler cause for any reason what will happen if IRF get a short? I went down this road and abandoned ship. The motor control board is bad and replacement costs $300. If possible I'll try to update the design in the above article soon. Should I use some bigger capacitor (the original board had a 470uF/400V one). I built the DC 180v motor controller using triac, the motor starts fine for 15 seconds or so then starts fluctuating in the speed till it stops!Any help would be appreciated. should i use 6A4? The idea with putting a powerful light bulb as a voltage divider is groundless because of the power it dissipates in the small area of the treadmills motor bay. Constant torque is achieved by the use of PWMs which prevent the devices from unnecessarily heating up yet allowing them to conduct fully during the ON states of the devices.So it's like allowing the devices to conduct fully with full power yet only at the desired slower speeds by breaking their conduction many number of times per second. Here's a simple PWM based motor speed controller circuit which can be used for controlling a treadmill speed right from zero to maximum. However, I want to add that i intend to run the motor from a 24V battery and not from mains. Proform Nordictrack Treadmill Motor Controller Lower Board Mc2100lts-30.
