In micro geared motor, various parameters affect the performance of micro geared motor, such as speed, voltage, power, torque, etc. The following Vic tech micro motor briefly describes the speed and torque parameters of micro motor.
Rotational speed is the speed of the micro motor at rated power, rated speed is lower than the maximum power speed under full load, micro motor torque is the size of the rotating force, the torque of the micro motor and the strength of the rotating magnetic field is proportional to the current of the rotor and proportional to the square of the current and voltage, the rotational speed is determined by the factors of current and voltage.
The torque of the micro geared motor is proportional to the strength of the stator magnetic field and the current of the rotor coil, and proportional to the square of the power supply voltage, so the torque of the micro motor is determined by the current-voltage factor. The speed of the micro geared motor is determined by the power supply frequency and the number of poles of the motor, and there is no direct relationship with the power. The power of the geared motor represents the output mechanical energy driving the mechanical load capacity.
The higher the number of poles of the miniature geared motor the slower the speed will be. Under certain power conditions, the higher the speed the lower the torque will be, and vice versa the lower the speed the higher the torque will be.
The relationship between torque and power of micro geared motor: torque = 9550 × power ÷ speed, such as the speed of micro geared motor is 216 revolutions per minute, the power is 0.77W, through 9550 × 0.77 ÷ 216 then the torque is 36.
The above is the torque of micro geared motor, more about micro DC motor share, please continue to pay attention to Vic tech micro motor.
