I am working on gear mechanism for controlling the two wheel at back of car with two DC motor of 24V .5HP......
so, no load RPM is 3000 i want to drive 15inch diameter wheel the front wheel are free. the required speed will be ~1meter/sec. not so fast
and RPM OF wheel at 100.
A 15" wheel at 100 RPM will go ~2m/s
please help with these gear as worm have been constructed but the output at wheel is at 60RPM torque is very very less for driving the load of ~80kg.
What is the loaded speed of the motor?
The unloaded speed doesn't say much, except that the gear ratio must be higher than 30:1, but not how much higher, so you need to find the loaded speed.
The two motors have 1hp total. In DK, a moped is limited to max. 1hp and 30km/h, with an adult rider and that's a bit over 8m/s, so you have ample motor power for 80kg at 1m/s (or 2m/s for that matter).
