The relationship between torque and current & various resistance is important in motor so in this study the motor properties is searched and find it can increase with current in different conditions which includes voltage, resistance of armature and times. The torque can increase with the current increasing. In terms of increasing the time to 140s the torque will increase certain. The maximum torque is 0.5Nm which is under condition of U=18V, Rm=8.5Ω& t=60s with armature radius of 5mm and its mass of 5.7g. The effective turn is U>Rm>t which expresses the prior factor among these three parameters.
