Could you show the purpose of equipment which is used by operator at 1:20 ?

[@Liam26011]

it's to see the magnetic field.so you know if it's going clockwise or counterclockwise

What this guy was doing at the end of video..?

Checking for rotation. When you do your full current test after rewind, you use a dummy rotor that checks to make sure your connection is correct. If you have a jumper that is off, you'll have a dead spot in that area in the stator.

Currently i am facing a problem With DC Motor.problem is mentioned below:
1. DC motor was overhauled.Rewound Field Interpole and armature windings.all windings are in good condition with 2000 Mohms value.
2.Polished and skimmed the commutator,,drop tested. found ok.
3.Brush and carbon holder is in good condition.
Now the problem is motor is giving heavy sparking on load. Application of motor is boom hoist motor.
On No load motors runs smooth no sparking,no vibration.
Why it's giving heavy spark on load and we opened twice the motor but not able to get the root cause.
Anything else that i need to check?
