What is A1 A2 motor?

What is A1 A2 motor?

Terminal screw means that A1 should always be connected to the source. A2 should always be connected to either S1 or S2 (depending on direction). The leftover “terminal” should be connected to the source. They’re just saying to always connect A1 to the output of the controller.

What is S1 and S2 on a 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.

How do you test a SepEx motor?

The best way to test a SepEx motor is to separately excite it. Always have the field on first and off last. Hook the F terminals to a power supply of the proper voltage range. A variable supply is nice because you can vary the field strength and see the effects on the motor speed.

What is P1 and P2 on a motor?

The difference between the power induced to the pump and the hydraulic power indicates the efficiency of the pump. 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.

What happens if you wire a DC motor backwards?

Reversing the polarity of the supply voltage will produce a force in the opposite direction, helping the motor to stop quickly.

What do the leads A1 and A2 mean on a motor?

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 is the difference between DC motor and DC series motor?

This type of DC motor is constructed such that the field is not connected to the armature. This type of DC motor is not normally used. The motor is called a “shunt” motor because the field is in parallel, or “shunts” the armature. The motor field windings for a series motor are in series with the armature.

What does the direction of the arrows in a DC motor indicate?

The direction of the arrows indicates the direction of the magnetic fields. This type of DC motor is constructed such that the field is not connected to the armature. This type of DC motor is not normally used. The motor is called a “shunt” motor because the field is in parallel, or “shunts” the armature.

What do the leads on a DCDC motor mean?

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.
