A typical 220-volt electrical outlet in the home is the most affordable power source for electrical appliances. Some electric motors can work from it directly, while others will need additional elements and nodes to be powered from such a network.
Instructions
Step 1
A single-phase asynchronous electric motor is designed for a voltage of 220 V. It is enough to connect it to the network. Remember, however, that the simplicity of connecting a motor of this type turns out to be a major drawback - a low efficiency.
Step 2
Two-phase motors, otherwise called capacitor motors, require two parts for operation: a paper capacitor for a voltage of at least 500 V (its capacity is indicated in the reference book or directly on the motor), and also, in some cases, a step-down autotransformer, since most of these motors are designed for voltages in 110 V. Apply this voltage directly to the one of the windings that is designed for direct connection, and to the remaining one through a capacitor connected in series with it. The use of any other capacitors other than paper capacitors is not allowed.
Step 3
Three-phase electric motors are not designed for operation as capacitor ones. Use them in this capacity only with a very light load on the shaft, otherwise it will stop and the windings will burn out from overload. At rated load, power such a motor only from a real three-phase network.
Step 4
To connect a universal motor (collector with series excitation), connect the excitation winding and the collector-brush assembly in series. Then, having previously loaded the motor shaft with the mechanism with which it will be operated (this is a prerequisite), apply the supply voltage to this series circuit.
Step 5
DC brushed motors are usually low voltage. To connect such a motor to a 220-volt network, use a power supply that is suitable for the parameters, which includes a transformer and a rectifier.
