2020年4月23日 · If the motor is spinning at 1000rpm, and you reduce that to 500 rpm with a 2:1. you have increased your torque by double and so on. To illustrate: a motor and generator can be the same thing if you reverse the direction the power input, So if you use a large slow torque, and increase the speed, you have the opposite effect and you can generate ...

2010年12月12日 · 2) A true torque motor can provide a fixed preset torque at a range of RPMs including both forward and reverse RPM, and zero RPM ("locked rotor"). The difference between these two motors is similar to the difference between a constant-voltage regulator and a constant-current regulator in electrical engineering.

2020年8月2日 · *Comparation of diesel vs petrol engine with equal power *Why all heavy duty-long last engines are low RPM? *Is low RPM main reason why diesel last longer then petrol engines?If does,why high RPM engines "kill" engine faster? *What are pros/cons for diesel and petrol in term of durability?

2018年9月24日 · I am looking to purchase a Low RPM, Very efficient DC motor/Generator between 200w and 1kw for a low friction fly wheel project which involves powering up a 10kg flywheel to about 50 RPM over say 30 seconds then recovering the energy back through the motor/Generator with minimal losses, ideally with losses less than 5%.

2021年1月19日 · It works fine but the problem is I have with this is that sometimes I might want 2 or 5 rpm (especially when lowering it the option to speed it up would be very handy). The disco ball motor has a set RPM of 1 and I cannot alter it on the fly.

2016年10月4日 · My experience was that this was a waste of time, the change in motor efficiency with RPM swamped changes in fan & housing efficiency. The motor manufacturers characteristic curves were not accurate enough to correct the problem, so I couldn't separate the change in motor efficiency from the change in fan efficiency.

2016年2月7日 · Low RPM, Very efficient DC motor/Generator, 200w to 1Kw. Sep 25, 2018; Replies 5 Views 3K. Troubleshooting ...

2018年3月6日 · A brushless motor controlled by an electronic speed controller can produce an accurate and relatively powerful system. Most BLDC motors used for hobby r/c equipment would be suitable and these are capable of supporting a significant axial and tangential load. When operating at low RPMs (2700 RPM is slow) good quality motors are virtually silent.

2020年6月28日 · Internal gear motors are better than external gear, but still prone to overheating at low speed. Axial piston motors start to grind the surfaces off their shoes at low rpm. The best option for high torque / low speed is a radial piston motor, but cost is …

2019年9月4日 · I'm designing a machine that I need to spin a horizontal disk at low RPM using a motor and gearbox. I'm not good at physics so I need help to find a motor/gearbox to fulfill my needs. It's a horizontal disk, a shaft is connected at the middle of the disk, connected to the gearbox on top of disk.
