motor control

Hello everyone... For some time now I've been thinking about developing a new way to control/command, sets of thyristors in anti-phase, using pulse width modulation (PWM), with zero-crossing synchronization (ZC). In fact, I had already used such resources, in temperature control for large...

I have developed a dimmer circuit for 1000w halogen lamp.... But the problem is that when voltage applied to lamp is less than 200v,it works perfectly. But when i increase voltage to 220v or connect circuit at nearest point to the power supply, the optocoupler stop wokering..... I have used two...

hey hope everyone is doing great, my name is QIK I’m a student working on designing a motor system for an e-bike project. I’m seeking guidance on the best practices for motor control, selecting materials for motor components, and ensuring efficient power management. Specifically, I need advice...

Hi, I am looking for some advice on wiring a single phase, 2 speed motor to an autotransformer 5 position speed controller. I have this fan: Helios SVS125B – Single phase, 2 speed And an ATC1-1.5A, 5 position speed controller. Wiring Diagrams: Fan: The motor side is already pre wired and...

Hello Friends, Is it possible to deduce the maximum no load speed of a brushless dc motor by the back EMF constant 'Ke' or from the motor velocity constant 'Kv'? I found this article that describes how to find the maximum speed and tried following the steps...

Guys, I don't know if I'm in the right place, I'm sorry if I'm not. My vacuum cleaner broke down. I think it might be the fuse on this electronic board. Could you tell which element is the fuse?

Hi all, I have the circuit attached as a way to ramp voltage up and down based on a customer's input of dual 4-20mA signals. This will then be turned into a PWM signal to control our motor. Is there a graceful way to handle the 4-20mA signals, as there can't be an instantaneous change. The ramp...

I have a tip36C transistor. If i connect the emitter to the positive terminal of a 3 volt battery and the collector to the negative terminal of the battery and the base is not connected to anything, it will turn on a motor. And If i connect the emitter to the negative terminal of a 3 volt...

I don’t know where this needs to go so I put it in general. I think I need a circuit to control a 6v motor with a on/off switch. I assume it would be 1) battery 2)switch 3)circuit 4)motor. I think I need a circuit that will run a motor for 1-3 seconds then stop for roughly 20 seconds then...

Hello friends, first of all sorry for my bad English. I am an electrical and electronics engineering student. I have a problem in my control systems lesson project. The project is about controlling a dc motor with adjustable current and same voltage on the dc motor. The professor gave us a clue...

Hi all! I am new here, so please guide me. I am currently working on a project which involves working with H-bridges for motor control. It is required that I am able to wire up the circuit and make it work. The only problem is that I am a Mechanical Engineering student, so I have no knowledge...

Hi, This post is more of a curiosity at the moment with potential to become something if I find a solution/idea. I am an extreme novice to all of this, especially motors and controlling them so please be gentle and patient. I most likely wont know many of the terms you use so please explain it...

I am using one machine (which has a small motor) which has battery of 1.2v which got dead and i want to change the power source to USB. The battery is of 1.2V and 400mAh. Motor connected to works perfectly fine if provide the 1.2V from bench power supply. I want to use USB power supply instead.

I've been using this MC2100 in conjunction with a pwm circuit I built, and had been using it successfully for a time on a bandsaw. I must have pushed it a little too hard when resawing a log, as the motor suddenly stopped in the middle of the cut. The behavior afterward was that turning it on...

I have to use a 94V battery to power a 24V DC motor and looking for suggestions on a motor controller that will help with the buck converter aspect and in rush current of the motor? Im a student so still trying to learn the best way to do this and was told this may be the best approach? The...

I am trying to control a linear drive motor with a built-in encoder. I am using a motor driver to move the linear motor. I have calculated a PWM signal for a PWM frequency of 1kHz and a duty percent of 50% with the following values: Internal Clock = 180 MHz Prescaler = 180 Arr register...

hi all I'm trying to control a 2 HP water pump works on one phase using 5V relay, but I feel it's not safe because it's pins are so thinner than the AC wires does using car cut-out relay will be good? should I use just one for the LIVE wire or two for LIVE and Neutral? note: contactors are so...

Hi, I bought a claw machine and there seems to be a problem with the motor control of the claw going up. when the claw is going up it will go for a brief period and then stop, the motor will stall and it throws an error (claw not going up) . Motor seems fine 28v 0.48a when powered with bench...

Hi, I work for company in the UK as an electrical engineer. I have just started at my new place and they have a 3-phase pump motor controller that needs replacing. It's a Coelbo Onematic controller, working off the pressure in the water line. I have a new controller unit but don't want to wire...

Hey everyrone, i have a question regarding a PSU i have at home (once used for a 3d printer). Its a 200 watt PSU 230V AC 2-3A (i think) step down to 24V (8.8A). I was hoping to jerry rig it to a 24v 12kW brushed DC electric oil pump (used for an emergency oil pressure system), i understand this...
