What should the armature gap measure?

The armature gap is an essential component in small motors, as it refers to the space between the armature and the stator. Maintaining the correct measurement of this gap is crucial for efficient motor operation, as it affects the magnetic field strength and the overall performance of the motor.

A measurement of 0.10 inches for the armature gap is optimal because it allows for effective magnetic coupling while minimizing losses due to air gaps. This measurement helps ensure that the armature can spin freely without excessive friction or wear on the components. If the gap is too small, it could lead to contact between the armature and stator, causing damage and operational failure. Conversely, if the gap is too large, it can result in decreased torque and inefficiency.

Understanding the correct measurement for the armature gap is vital for anyone working with small motors, ensuring that they can maintain or repair these devices effectively.
