A 6V DC brushed motor with a 588:1 worm reduction gear. A candidate for driving the rudder of a microtransat sail boat. P.S. I wrongly described the case of this motor as diecast aluminium. I think it is in fact stainless steel.
Thank you for your video. I have have son meganic lying here for more than 3 years 12V - 30 rpm, today I am going to make finally a linear actuator to to regulate the speed of my diesel generator. I make a simply construction with metal corner brackets, later i will place photo's.
That's the problem, i don't know how fast it will go. Can't find any video on car or robot that is using 220 RPM motors with wheels directly mounted. I want to use two RC ESC do to control speed of two motors of each side and to control turning. I don't wan't i to be too fast but keep up to RC models to be able to film it. By the way, i think you are very inteligent person and i mean it.
Well your platform speed will be 2 * PI * Wheel radius * Motor speed in RPM. And the units of that speed will be X per minute where X is the unit you measure the wheel radius in. E.g. If you measure the wheel radius in cms then the speed will be cms per minute. Compare this with the RC car speeds. This assumes the motors have adequate torque to push your platform at their rated speed.
Hi all, you will find a thorough testing of this motor here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ynh-ik3KGtM.html github.com/OpenTransat/ServoEncoder It's the origin of the idea of using this motor. I have been testing many motors/servos/actuators and this one has survived over 3 million cycles which makes it very suitable for the transatlantic attempt. You will also find the code how to get position feedback using a magnetic encoder. There is more to be developed like receiving feedback when the motor is stuck. Andy @ OpenTransat
Bought some of these and motor separated from gear box on two of them Screws backed out for some reason. One on first very light use. The other had been used a little. Any idea how to prevent this.
There are two answers to this. (1) There is almost no rotation if you grab the output shaft and try to turn it by hand. (2) There is some backlash between turning the shaft of the motor and then this turn appearing on the output shaft. I have not measured this on this gearbox. It will mean, for example, if you drive the motor one way, and then reverse it, there will be some rotation of the motor before the output shaft reverses.
Probably. It depends how the 1.5Kg thing is supported and if it is symmetrical about the axis of rotation. It doesn't actually require any force to rotate a round object, such as a turntable or flywheel, beyond the force needed to overcome bearing friction and get the thing moving.
