Motors & Power Transmission

Motors are electrical devices that convert electrical energy into mechanical energy. They operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Motors can be powered by direct current (DC) from a battery or by alternating current (AC) from an electrical power grid or electrical generator.

Power transmission products transmit power to create motion. They are commonly used in industrial automation, material handling, and construction applications. Rotary motion devices transmit power between rotating parts in a machine. They include chains, belts, pulleys, sheaves, and gears. Linear motion devices transmit power and support motion in a straight line. They include actuators and linear bearings. Bearings extend the working life of wheels, pulleys, and other rotating parts by reducing friction and enabling parts to move smoothly.
