What is a P1 wire?

P1 is a label of power cable that connects the power supply to the motherboard. See the ATX style connector definition for further information about this connector.

What is S1 and S2 on DC motor?

DC motor terminal leads are labeled for easy identification in the motor’s terminal box. For example, leads labeled “A1” and “A2” are connected to the armature through the motor’s brushes; leads labeled “S1” and “S2” are the ends of the series field; and leads labeled “F1” and “F2” are the ends of the shunt field.

What are P leads on a motor?

The “P” in P-lead comes from the primary winding in the magneto’s coil. To deactivate the magneto, the primary winding is grounded. An ignition switch opens and closes the P-lead circuits to a suitable ground.

What does P1 mean on electric motor?

P1 is the total induced power to the pump system. P2 is the power coming from the motor (shaft effect). P2 is the nominal power of the motor.

How many leads does a DC motor have?

Your motor will be supplied with either a single voltage or a dual voltage shunt field. Single voltage shunt fields have only two field leads (F1, F2) while dual voltage shunt fields have four field leads (F1, F2, F3, F4). Leads P1 and P2, when supplied, are from a thermal sensor element attached to an interpole coil.

What are the 3 types of internal wiring of a DC motor?

There are three types of electrical connections between the stator and rotor possible for DC electric motors: series, shunt/parallel and compound (various blends of series and shunt/parallel) and each has unique speed/torque characteristics appropriate for different loading torque profiles/signatures.

How do I know if my motor is 110 or 220?

If the wires feeding it are black and white, with no colored phase tape on the white wire, that could be a clue that it is 110 V. If there is a band of red or blue tape on the white wire, that would be a clue that it is wired for 220V.

How do P Leads work?

(The “P” stands for”primary.”) Its purpose is to allow the ignition switch to disable the magnetoby grounding the hot side of the primary. As long as the P-lead is grounded through theignition switch, the breaker points are unable to interrupt the primary current flow,making the mag incapable of generating a spark.
