Why would you megaohm a motor?
To determine whether there are any electrical shorts among windings, or from windings to case ground.
What are the possible cause that motor compressor trip?
there is a possibility that parts of motor windings has partial damage.
An important difference between a universal and a split-phase motor is that the split-phase motor has?
two windings on the stator
Is the dc shunt motor does not have any brushes?
No. A d.c. 'shunt' motor is one whose stator's field windings are connected in parallel with its rotor windings ('shunt' is simply an archic term for 'parallel'); it does not mean that the rotor can function without brushes.
What are motor made from?
an electric motor is a copper winding or 3 separate windings depending on the phase, the copper winding is the centralised inside of a iron magnet, this is also how a generator is made instead of putting a current on you turn the windings to receive a voltage .
The windings of an AC motor are called?
Windings
What happend when you start motor without starter?
The windings of the motor will be gonebecause of high current diectly goes to the windings of motor.
How Synchronous motor work with principal?
A synchronous motor comprises of a stator windings and a rotor with a squirrel cage and inside that is windings(coils). At starting, this motor is an induction motor running with slip. After the rotor has reached a certain speed, a DC current is applied to the windings inside the squirrel cage. A fixed field is induced in these windings. This field locks in with the synchronous rotating magnetic flux of the stator windings. The rotating stator windings then pull the rotor along. The amount of excitation current can be used to control the power factor of the motor, making this a popular type of motor for high power use with a constant mechanical load.
What is the function of the overload protector?
The bimetallic overload protector is mounted in series with the motor windings. Should the current in the motor windings increase to a dangerous value, the heat developed by the passage of the current through the protector will cause it to open. This breaks the circuit to the motor windings and stops the motor before any damage can occur.
What is the function of overload protector in refrigerator?
The bimetallic overload protector is mounted in series with the motor windings. Should the current in the motor windings increase to a dangerous value, the heat developed by the passage of the current through the protector will cause it to open. This breaks the circuit to the motor windings and stops the motor before any damage can occur.
What is interpole winding in DC machine?
For a D.C motor it is the field windings which must always be in series with the armature windings.
Why would you megaohm a motor?
To determine whether there are any electrical shorts among windings, or from windings to case ground.
What type of dc motor has its field winding in parallel with its armature windings?
Shunt Motor
How is a DC permanent-magnet motor reversed?
Reverse the polarity of armature windings of the motor.
How do you you cover exposed motor windings?
You don't. Motors have vents to dissipate heat. Although you can see the windings through these vents, don't cover them or the motor will overheat and burn up.
Why a starter motor solenoid has two windings?
to move the plunger in and out
What is shunt and series motor?
A series motor is one in which the field windings are in series with the armature windings. So the torque is proportional to the square of the supply current.'Shunt' is an archaic term for 'parallel'. So a shunt motor is one in which the field winding is in parallel with the armature windings. So the torque is proportional to the supply current.
