Earth's Spin & Moon: Impact on Rotation

[termina]

Hello there!

When a motor is turning, if one applies a resisting torque on the rotor,
the latter would brake, but then if one remove the torque,
the motor recovers its initial speed.

Is the same with Earth's spin and Moon's resisting torque on it (due to tidal effect)?
ie: if, one day, the aforementioned torque is put off, would our planet recover its initial spin rate?

No. The motor is driven from an outside power source which supplies the energy needed to bring the motor up to speed. The Earth's spin is just due to its own inertia and there is no power source to speed it up again.
