In order to keep the motor running smoothly, use permanently lubricated sealed bearings to protect against contamination and friction loss.
Continuous duty (or induction) motors are rated for continuous operation within the stipulated temperature range, wherein, the motor runs with a constant load for a long duration to reach thermal equilibrium.
Single-phase motors use a capacitor to provide additional power during motor startup. These motors are ideal for equipment and machines that are smaller in size and need lower horsepower.
