Hi Andy,
We are frequently asked if we can provide a motor for a consumer product and it's rare that we can help. It's just that there are simply hundreds of different specifications for the motors even though they may look identical. The nearest we have is our model motor size B but the physical size is slightly smaller. It is also possible that the rpm and power is quite different.
Sorry we cannot be of more assistance. |

I am looking to find a motor that can acheive the following:
- Run at low speeds
- easily adjustable though, able to speed up or slow down.
- Quiet
- timed (turns on and off every so often)
Does not have to be just one product just most suitbale and easy to use.

James,
There is almost certainly a suitable product in our range but we need more information:
Maximum speed in rpm
Voltage
Torque or motor power
Shaft size
You say quiet but what do you call quiet?
For timing, we do not have any specific for this but we may well have a solution once we have the motor selected. |

it doesnt have to be very fast at all, it's more a case of 20-40 rotations an hour.
For torque im not very sure how much i need, but i'm trying to make a display model that rotates, which wont be very heavy, a couple of kilo at the maximum.
when considering voltage, i know little about quite what i need, i was hoping you could suggest the ideal voltage.
shaft size is not my greatest worry, anything that i can fit a cog to.
When i say quiet, i was hoping to have a motor that made almost no noise, very discrete, no whirring or anything noticable.
Hope this helps.

James,
Okay, you have a speed of 0.333 to 0.666 rpm Our geared motors only go down to some 3-5rpm so you would need a further reduction using gears or pulleys. Do you wish to run off batteries and do you need to vary the speed?
Nonel of our motors are designed for quiet running and will be spinning at anything from 5 to 10,000 rpm. The only thing I could suggest is to mount the geared motor in a sound proofed box with a pulley belt coming out to drive your turntable. You may be better off using an old record turntable motor but many of these are mains powered and you would still need further reduction. I don't think we can help with the running noise being as low as you need. |

I do plan on running them off a battery, and i no longer need to vary the speed, and just run at a constant speed.
thanks

James,
The largest reduction ratio we supply is 3000:1 and you will need between 5 and 10:1 further eduction to get your desired speed. Maybe have a soft rubber wheel on the end of the geared motor to drive a turntable around. Just a thought, check out our 1450-106 or 1450-056 for further information. |

Can you suggest a source for the following motor: 41TYZ-B Synchronous Motor, 12 VDC, 5 RPM, 1/2 W. The motor is used to drive a multi-color strobe wheel. |

Hi,
If you check out the first post of this thread you will see that this question has been asked before and that we cannot help. We would Email you but you have not provided your address. |

Hi,
I have a fiber optic poinsetta tree that changes color with a color wheel attached to the motor inside. My question: Where can I get a new motor, the one inside does not turn the color wheel anymore. Here is the information that I have. The motor had this on it... 41TYZ-B Synchronous Motor AC 12V 50/60HZ 1.5/2W 5R/min CW/CCW. It has a 2" rod that extends from the top where the little color wheel sets on. Can You help? I copied all this down from what my Husband left on a paper, I just hope I read it right. |

We are starting to think there is something more to this as this is the third request for this particular synchronous motor (see post immediately above). We would have Emailed you but you did not leave an address. |

Dear Technobots,
I am looking to install a projector into the ceiling of my lounge, it will be attached to a hinged door that is cut into the ceiling and I am looking to somehow lower the lid appx 6" to allow the projector to 'peek' out.
I am looking to do this electronically/motor driven and have the control of this remotely either wireless of wired.
I have looked into a Satellite Actuator arm that is attached to a pulley mechanism that lowers the flap down, but i was wondering of there was an alternative solution that could be done?
Regards,
Jamie |

Jamie,
If I was to undertake this project, I would use a low voltage linear actuator which you can pick up cheaply from Ebay. Operation would require a reversing supply (typically 24V) so hard wired would be very easy. We have suitable power supplies and relays but not the linear actuator.
You could use a geared motor with a pulley which we do have in stock.
We would have Emailed you a copy of this post but you did not provide an Email address. |

John,
Thank you for your enquiry but we currently do not supply any coreless motors on their own.
Sorry we cannot help. |

Hi, I am contemplating a 1/5th scale buggy with electric power. Do you have any experience of likely motor battery combinations with respect to a 2WD (with diff) chassis at about 10Kg? I am considering a single 200W motor, a pair of 12V 3Ah nimh packs and a 30A speed controller. Hoped for performance is (say) 20mph and the ability to get up a 30 degree slope. Any thoughts or comments would be muchly appreciated.
Regards, Pete
PS you may remember me from RobotWars days, Team UFO and 51?? |

Hi Pete,
Certainly do remember you from the 'old days', I trust you are well.
Sorry but no experience of your application but naturally we have of 12kg featherweight robots. As a rule of thumb, 15W/kg is a good starting point for you so 200W does not sound too far away. Weight is the issue for your use, there are plenty of high performance motors out there for model cars so do you have room for a 'conventional' motor? If you do, take a look at our 1470-014 200W 24V motor which offers plenty of torque. As for batteries, you will need some good quality packs that can withstand continuous currents of 15A ish. Our 12V Hi-Energy packs will be up to the job. For a speed controller, our Electronize 30A controller with external relays will be fine as will our 20A H Bridge controller.
Hopefully that gets you started.
Regards
Paul |

Hi Paul, Thanks for the swift response regarding my 1/5th buggy question, much appreciated! I'm well thank you, keeping busy. Looks like you are too..! Your suggestions fitted well with my own thoughts so one further question; what is the spec/dimensions of the pulley on the 1470 motor and is it easily removable/replacable? I will need to go to a gear compatible with the diff in the buggy chassis (looks like a module 1 gear to me). Order to follow...
Thankls again and regards, Pete |

Hi Pete,
Always too busy myself! The pulley can be removed by removing a circlip and pulling off the pulley (its a shaped shaft from memory) although it can be tight but are only a push fit on.

Hi, I am planning to put a laptop on wheels, and I'm looking for some geared motors and wheels to drive it around a large (50 square meters ish) flat open plan office. The laptop could be about 3kg. I need some advice about which motors to buy, and wheel size for enough torque for it to be responsive and but to cope with 50m drives without killing the battery. Would any of the Tamiya geared motors be ok? I was expecting to use an RC 7.2v battery for 6v motors via the motor controller card. |
