Further Information

Where can I find the mounts for this product?
Asked by: harjee

Hi Harjee, Currently we don’t stock a mounting bracket/clip for this motor. We do stock a mounting clip which can be used with another high torque motor, https://kitronik.co.uk/products/c2507-motors-high-torque https://kitronik.co.uk/products/2505-plastic-motor-mounting-clips-pack-of-10

does this produce power
Asked by: craig
Hi Craig, Thank you for your question, I assume you mean using this much like a wind turbine so when the propeller turns it will generate some current and voltage but not loads and it would need reasonable force to turn it. Best Regards Cullen

Can you recommend some 12 volt batteries to use with this motor to get the best speed and performance that you or any other retailer sell?
Asked by: David
Hi David, We only have 1 12V battery, however it has a low capacity so wouldn't be great for high current draw items. The motor can run on a voltage between 6-12V, so you could use 4XAA batteries to give 6Vs, a 9V battery or even a 12V mains power supply. Looking at the datasheet the manufacture has performed tests from a 7V supply, which at maximum efficiency gives an RPM of 17512. If you are wanting to use 12V however you can perform calculations here to find out the maximum efficiency at 12V, http://simplemotor.com/calculations/

I bought a power supply that is 12v 5a DC, however when I connected the wiring the motor was pulsing and not spinning consistently. Why is this?
Asked by: John

Hi John, It sounds like when the motor is initially turned on there is a spike in the current it draws, this then causes the power supply to shutdown to protect the circuit from overload. It will then detected that the current spike has gone and apply power again. This would then result in the pulsing motor you have described. However it is slightly difficult to recommend a fix as we don’t know what other circuitry you are using and how the motor is connected.
