These devices convert electrical energy into mechanical energy through the action of magnetic fields generated in their coils. Ideal for general uses such as cooling ventilation and applications where power is required. Manufactured in cast iron, it provides power and resistance during its use, besides it is of armored type, which allows it to be efficient, practical and easy to start. Thanks to its design, it facilitates the connection of the coolant fan. Being 18 watts, 127 volts and 1550 rpm, it helps to optimize its use during practice.
