ANSI/IEEE Single-phase synchronous motor form

IEEE-library form of single-phase synchronous motor: this representation identifies a single-phase synchronous machine function.

In plain English

What does ANSI/IEEE Single-phase synchronous motor form mean?

This reference locates single-phase synchronous motor in Autodesk's IEEE-oriented 1 phase motors family. This representation identifies a single-phase synchronous machine function. The public library uses HMO1M16 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number.

A simple example

Trace each winding, supply and accessible neutral through the complete machine or transformer connection diagram. Keep the phase arrangement, terminal labels and any clock notation attached to the device; neither the convention label nor this educational outline supplies its ratings.

What the drawings help you do

State the supply, starting and any excitation interface required by the actual motor. Synchronous operation differs from induction-motor operating slip. State the supply, starting and any excitation interface required by the actual motor. Synchronous operation differs from induction-motor operating slip. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted.

How to read it

  • State the supply, starting and any excitation interface required by the actual motor.
  • Synchronous operation differs from induction-motor operating slip.

Information to show or reference

  • Identify the associated device, circuit or diagram boundary.
  • State the supply, starting and any excitation interface required by the actual motor.
  • Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.

A distinction that matters

Synchronous operation differs from induction-motor operating slip.
