Описание товара







PTK 8840 TG-D metal digital steering gear High torque 24KG 7.4V high pressure / hollow cup servo 0.12 seconds
Hollow cup motors mainly have:
1. Energy-saving characteristics: The energy conversion efficiency is very high, and its maximum efficiency is generally above 70%, and some products can reach more than 90% (iron core motors are generally 70%).
2, control characteristics: start, brake quickly, very fast response, mechanical time constant is less than 28 milliseconds, some products can reach less than 10 milliseconds (iron core motor is generally more than 100 milliseconds); high-speed operation in the recommended operation area Underneath, the speed can be easily adjusted.
3, drag characteristics: the running stability is very reliable, the fluctuation of the speed is very small, as the micro motor, its speed fluctuation can be easily controlled within 2%.
In addition, the energy density of the hollow cup motor is greatly improved, and the weight and volume are reduced by 1/3-1/2 compared with the iron motor of the same power.
