Per code the earth should never be used as the sole source of ground. So no.

What is earthing of electric motor?
This is avoided by grounding the motor frame. Both methods effectively produce a solid electrical connection straight to the stator laminations, allowing any insulation failure to be grounded via the end-ground user's conductor. Earthing is a technique in preventing electric shocks. To start, virtually all electric motors require grounding. The neutral earthing is given in the generator, transformer, motor, and other electrical devices by connecting the non-current carrying section to the neutral earthing.
On a 220 volt electric motor which is the neutral wire L1 L2 or L3?
If the motor wire numbers are L1, L2 and L3, it is not a single phase motor. It is a three phase motor. Also for future reference, a 220 volt single phase motor does not use a neutral.
Does a three phase motor have a neutral?
No, three phase motors do not actually have neutral line unless you are referring to the motor control centre where a neutral line is required when your control coils and other components are single phase operated
How can you find motor FLA without the motor nameplate The motor is single phase 120 vac?
use clamp on amp meter
Why neutral not conect in 3phase motor?
A 3 phase motor does not require a neutral conductor because the impedances that make up the stator coils are of equal magnitude and it is what is known as a balanced 3 phase load. If the loads of a wye connected 3 phase system were unbalanced, i.e. the load currents in each of the 3 phases are different, then the unbalanced currents would require a return path to the service transformer via a neutral conductor. The neutral conductor is the transformer centre tap and is usually earthed locally. ANOTHER ANSWER The impedance of each phase winding of a three phase motor is identical (we call it a 'balanced load'). For a star (wye) connected motor, the phasor sum of three identical phase currents is zero, so no current will flow through a neutral, so a neutral isn't required. For a delta-connected motor, there is no provision for a neutral.

Is there any current flow through the neutral wire of single phase motor?
Yes. It is identical to the line current.
How many wires in a single phase motor?
There should be 2 or 3 wires. A hot, a neutral and sometimes a ground.
How do you select earthing conductor size of any motor panel etc?
The ground wire size is determined from the current carrying capacity of the motor feeders.
How do you put a 2004 Pilot in neutral with the motor turned off?
You cannot put a vehicle in neutral when the motor is turned off. You can put the vehicle in neutral while the motor is running. Then you can turn the vehicle off and the vehicle will remain neutral.
When does a motor not need a neutral wire?
If the motor is operated from a three phase three wire distribution system the motor will not need a neutral wire.
How can you find motor FLA without the motor nameplate The motor is single phase 120 vac?
use clamp on amp meter
Will the neutral switch stop the sparks To coil?
Yes. It prevents the motor from turning over while in gear without the clutch depressed.
How do you use a one phase motor in place of a three phase motor?
To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
Why ground the neutral of a 3 phase ac motor?
In a three phase motor each leg (3 phases) in the down cycle alternating at 1/60 per second servers as a neutral, you are only required to ground (green) the frame of the motor for safety. This is similar In a single phase motor wired for 240v (2 phases) the same thing happens and you are only required to ground (green) the frame of the motor for safety. From: Ken F
