8Pack DC Motor 3V-12V 280 Micro Motor 42 x 24 mm for RC Boat Model Toys DIY

plenty power as well as speed, and torque

Great Motors

I bought these to replace the 12V motors used in my campers bunk end lights/fans. Same size. Before installing I hooked the motor up to a 12 VDC laboratory power supply. With no load They were pulling less than an Amp of current. When I installed the fan blade (about 4.5 inch in diameter) to the shaft and powered it up, the motor started pulling almost 5 Amps. This was alarming, but I didn't measure the current draw of the old motor before it died so I had nothing to compare it to. Next I installed it in my application and it refused to turn. The light/fan has two speed settings so I bypassed these controls to power the fan directly. It spun, then smelled and finally smoked. Well, that's why I bought extra. I hooked up another motor to the power supply and installed the fan blades onto the shaft. I let it run, and it smoked it self in less than a minute. Bottom line: these are not 12 volt motors. So I am returning them and will keep looking.

These motors do have a hefty amount of torque for their size, much better than using standard 130 motors. I think these would be best suited for devices that require a lot of torque, fan blades, propeller blades, props on boats and the like. DON'T LISTEN TO THE ADVERTISING, THE VOLTAGE RANGE IS NOT CORRECT. Voltage on the low end is whatever will turn the motor for your needs, voltage on the high end however is a maximum of 7.20 volts, this is rated voltage, which is expressed in terms of the maximum safe voltage the motor will handle. See attached... 【Specification】total length：45mm，shaft length：11mm，Rated voltage: 7.2V 380mA 13500 rpm，No-load voltage/current: 3V 250mA 6800 rpm，6V 350mA 11000 rpm，9V 420mA 16800 rpm At 7.2 volts you'll get about 12,000 RPM, that's not bad considering most high torque motors have slower running speeds. I'd buy it again, actually I think I'll throw some on the list while I'm thinking about it. These motors sit right in between lightweight mini electric motors (130 motor) and much larger and heavier motors, these are good for when you want to keep the weight down such as in a drone, at two bucks a pop it's a pretty good deal...

Had to replace a motor on my son’s toy. Works great I think even better than the original motor. Now I have extras for the next toy replacement. I would purchase again if I required more.
