Whether adding to a system or troubleshooting these diagrams are an essential tool in every installers toolbox. The illustrations below schematically show the different methods of connecting the field and armature circuits in a dc motor.
The four leads and the way they are marked tell you this.

What s included oem wiring diagrams fuse panels and symbol identification images.
Apparently the motor you re grappling with is a shunt wound motor. Question 1 how is it possible to electrically measure the torque output by a permanent magnet dc motor. Wiring diagram for dc motor potentiometer and on off switch.
The circular symbol represents the armature circuit and the squares at the side of the circle represent the brush commutator system. I recently replaced an old 200hp louis allis magnatek dc drive with a new 200hp baldor bc19h series drive. Could someone please help me out by providing a wiring diagram for my dc motor that i am trying to wire to a kjd22 on off switch and potentiometer.
After installation and a successfull startup i noticed the f2 f3 a1 leads were all terminated together at the motor with the a1 armature lead from the drive f1 f4 tied to drives f f. It is very simple and for large electric motors it involves the use of a shunt resistor modify this circuit diagram to include a meter that provides indirect indication of motor torque. There are two terminals and when you apply direct current to one terminal and ground the other the motor spins in one direction.
The direction of the arrows indicates the direction of the magnetic fields. Motor connections your motor will be internally connected according to one of the diagrams shown below. Wiring diagrams provides precise and comprehensive diagrams as published by the original equipment manufacturer oem.
Figure 4 shows a photo of a small dc motor. The dc motor is the simplest of the motors discussed here. The field is in this case an electromagnet and the two leads marked f1 and f2 are the field connections that go to a dc source field supply.
Assuming this was incorrect i had the f2 f3 leads isolated from the a1 lead in doing so the. Optimized for rapid retrieval easily navigate by system or search by keyword. The starter motor is an electric motor that turns over or cranks the engine to start.
The other kind of dc motor is a wound field or a shunt shunt motor. It consists of a powerful dc direct current electric motor and the starter solenoid that is attached to the motor see the picture. When you apply current to the other terminal and ground the.
