Set of 8 rivets, for those that want to pull their worm drive apart to either change the output shaft, or remove itSpeed, torque, power and voltage are all important considerations when choosing a motor.

AC motors are unique because they are built to run at specific speeds regardless of their design or manufacturer.

Common AC motor units are constructed with either two or four poles. A magnetic field is created in the stator poles that induces resulting magnetic fields in the rotor which follow the frequency of the changing magnetic field in the stator. Two pole AC motors operating at 60 Hz will always run at approximately rpm, and four pole AC motors will have speeds around rpm.

Keep in mind that the speed of an AC motor will not run at these exact numbers—and will be slightly lower—because there is a certain amount of slip that must be present for the motor to produce torque. The rotor will always rotate slower than the magnetic field of the stator and is playing a constant game of catch up.

This produces the torque to get an AC motor running. The difference between the synchronous speeds of the stator and rpm and the actual operating speed is called slip. A control can be used to alter the speed of a three phase AC motor by increasing or decreasing the frequency that is sent to the motor, causing it to speed up or slow down.

These motors are plugged directly into a standard wall outlet and operate using the set frequency available. An exception to this rule of thumb would be a ceiling fan that runs using single phase AC motor, but has three different speed settings.

The number of wire turns in an armature, the operating voltage of the motor, and the strength of the magnets all affect motor speed. If a DC motor is running on a 12 V battery, that is the maximum voltage available to the unit and the motor will only be able to perform at a speed rated for 12 V.

If the battery is low and supplying less voltage, the speed will decrease accordingly. DC controls adjust speed by varying the voltage sent to the motor this differs from AC motor controls which adjust the line frequency to the motor.

Typical no load or synchronous speeds for an AC fractional horsepower motor are or rpm, and rpm for DC fractional hp motors. Narrow your search by selecting motor type, gearbox, voltage, and phase options for your desired motor.

You should remember from basic electrical theory that a parallel circuit is often referred to as a shunt. Since the field winding is placed in parallel with the armature, it is called a shunt winding and the motor is called a shunt motor. Figure shows a diagram of a shunt motor.

Notice that the field terminals are marked Fl and F2, and the armature terminals are marked Al andA2. You should notice in this diagram that the shunt field is represented with multiple turns using a thin line.

The shunt winding is made of small-gauge wire with many turns on the coil. Since the wire is so small, the coil can have thousands of turns and still fit in the slots. The small-gauge wire cannot handle as much current as the heavy-gauge wire in the series field, but since this coil has many more turns of wire, it can still produce a very strong magnetic field. Figure shows a picture of a DC shunt motor.

A shunt motor has slightly different operating characteristics than a series motor. Since the shunt field coil is made of fine wire, it cannot produce the large current for starting like the series field. This means that the shunt motor has very low starting torque, which requires that the shaft load be rather small.

When voltage is applied to the motor, the high resistance of the shunt coil keeps the overall current flow low. The armature for the shunt motor is similar to the series motor and it will draw current to produce a magnetic field strong enough to cause the armature shaft and load to start turning.

Like the series motor, when the armature begins to turn, it will produce back EMF. The back EMF will cause the current in the armature to begin to diminish to a very small level. The amount of current the armature will draw is directly related to the size of the load when the motor reaches full speed. Since the load is generally small, the armature current will be small.

When the motor reaches full rpm, its speed will remain fairly constant. When the shunt motor reaches full rpm, its speed will remain fairly constant. The reason the speed remains constant is due to the load characteristics of the armature and shunt coil. You should remember that the speed of a series motor could not be controlled since it was totally dependent on the size of the load in comparison to the size of the motor.

If the load was very large for the motor size, the speed of the armature would be very slow. If the load was light compared to the motor, the armature shaft speed would be much faster, and if no load was present on the shaft, the motor could run away. The shunt motor's speed can be controlled.

Low RPM AC Gear Motors

The ability of the motor to maintain a set rpm at high speed when the load changes is due to the characteristic of the shunt field and armature. Since the armature begins to produce back EMF as soon as it starts to rotate, it will use the back EMF to maintain its rpm at high speed. If the load increases slightly and causes the armature shaft to slow down, less back EMF will be produced. This will allow the difference between the back EMF and applied voltage to become larger, which will cause more current to flow.

The extra current provides the motor with the extra torque required to regain its rpm when this load is increased slightly. The shunt motor's speed can be varied in two different ways. These include varying the amount of current supplied to the shunt field and controlling the amount of current supplied to the armature.DC motors use direct current to produce rotational motion. These motors have two primary parts: the the stator and the armature.

The stator is bolted to the motor housing and does not move. The stator can either be composed of permanent magnets, like in small DC electric hobby motors, or it can be composed of electromagnets. The armature is connected to the rotating shaft and also has an electromagnet. During normal operation the magnetic field of the armature and stator interact, forcing the armature and the main shaft to rotate. Connect one side of the DC electric motor to the negative terminal on the variable DC power supply, using the 12 electrical wire.

Connect the other side of the DC motor to the center terminal on the variable resistor if the resistor has three terminals. Connect one of the other resistor terminals to the positive side of the power supply using the 12 electrical wire. Make sure the resistor can handle at least the same amount of power as the motor.

Set the power supply at the rated voltage of the motor and turn it on. The motor should start running. Change the resistance of the circuit by rotating the resistor shaft. The motor speed should change. This changes the voltage the motor sees at its terminals. Reducing that voltage reduces the magnetic field at the armature. The same principle holds true if the the voltage at the power supply is changed.

Choosing appropriate resistors is important. In addition to resistance, resistors are rated by their ability to dissipate heat. This is measured in watts. When choosing a variable resistor to be used with a DC motor, the resistor wattage rating should be at least equal to or higher than the wattage rating of the motor.
