る。Figure 2 shows the force induced in the coil when a current is passed through the coil placed in a magnetic field.The armature coil is embedded in the armature attached to the rotating shaft 6. 9
The forces F1, F2, F3, and F that act on the coil 9 due to the action of the magnetic field φ of the permanent magnet 4 when a current ■ is passed through are shown.
ここで力Ｆ１、Ｆ２はモーターの回転に寄与する力とな
り、Ｆ３、Ｆ、はモーターの回転には無効な力となる。Here, the forces F1 and F2 are forces that contribute to the rotation of the motor, and the forces F3 and F are forces that are ineffective to the rotation of the motor.
このモーターの回転に無効な力は、電機子を振動させ、
モーターの機械的ノイズの原因となり、モーターの寿命
に悪影響を及ぼしている。This force that is ineffective in rotating the motor causes the armature to vibrate,
This causes mechanical noise in the motor, which has a negative impact on the life of the motor.
