바이메탈 기어박스 TT 모터 -1:90 기어비
(TT Motor Bi-Metal Gearbox - 1:90 Gear Ratio)
개요
- 본 제품은 바이메탈 기어박스를 가진 TT 모터 입니다.
- 견고하며, 1:90의 기어비를 가지고 있는 제품으로 표준 제품인 1:48에 약 두배의 기어비를 가지고 있습니다.
- 이러한 기어비로 좀더 높은 토크를 가지며 회전 속도는 그에 비례하여 느려집니다.
- 속도보다 힘이 필요한 곳에 사용하면 적합한 제품입니다.

You can power these motors with 3VDC up to 6VDC, they'll of course go a little faster at the higher voltages. We grabbed one motor and found these stats when running it from a bench-top supply
- At 3VDC we measured 80mA @ 60 RPM no-load, and 0.5 Amps when stalled
- At 4.5VDC we measured 90mA @ 90 RPM no-load, and 0.8 Amps when stalled
- At 6VDC we measured 100mA @ 120 RPM no-load, and 1.0 Amps when stalled
Note that these are very basic motors, and have no built-in encoders, speed control or positional feedback. Voltage goes in, rotation goes out! There will be variation from motor to motor, so a separate feedback system is required if you need precision movement.
Comes 1 x per order, with just the motor. These motors do not come with wires attached, so you'll need to solder wires on yourself.
You cannot drive these directly from a microcontroller, a high-current motor driver is required! We recommend our DRV8833 motor driver for these motors, as it works well down to 3V and can be set up with current limiting since the stall current on these can get high. The TB6612 can also be used, it's on our shields and wings, but you'll need to supply at least 4.5V - which is what you'll likely want to run these motors at anyhow!
We have a range of wheels, add-ons and accessories for these motors so you can bling out your bot just the way you like.
