Model aircraft, car model of brushless motor problem, how much is the motor torque 2000 kv
brushless motor starting torque is small, should pay attention to when using. 。
the problem of torque, = power/speed for general motors, torque (What motor are all the same, conservation of energy)
no one ask the motor torque, are related to your work speed.
as for the brushless motor, kv2000 no-load speed * 2000 = supply voltage (rpm)
of course, after the connected to the load torque will decline. Say is rated power (1300 wThe power of rated voltage under rated load)。
but how much is the specific work speed, which is determined by the size of the load. The motor when the load is connected, model aircraft motor, speed will fall (Torque will rise)Until the motor output torque is equal to the load torque and rotational speed is stable. And, therefore, cannot say one motor & other; What is the torque & throughout; 。
so how to choose the motor?
choose motor a premise is: the speed you need x your load torque & lt; Rated power = x rated current, rated voltage
visible, rated power refers to the motor with rated voltage, rated load (When electrical current is rated current)Under power.
from practice speaking, you can let the power of the motor with rated voltage, brushless motor, and then let it drive the load, see if it can meet your requirement of speed. While monitoring the current size. If more than rated current, the motor is not applicable.
