Vertical Hollow Shaft:
Vertical Hollow Shaft motors are designed for use on turbine, mix flow and propeller pumps. They feature a P-Base style mount where the line shaft goes up through the motor and out the top where it is secured. Vertical Hollow Shaft Motors are available in Totally Enclosed Fan Cooled and Weather Proof I enclosures with normal, high, and extra high thrust capabilites.
ESR Motor Systems is a leading distributor of Vertical Hollow Shaft motors and we stock a wide range of vertical motors in our warehouse in Rock Hill, SC.
Vertical Motors
The solution came in 1922 when engineers from U.S. Electrical Motors-a small Los Angeles-based motor company-developed the first vertical pump motor. The motor revolutionized the pumping industry and made irrigating large areas of cropland possible. This innovation helped make California the nation's top farming state, despite its limited water resources.
Putting an electric motor on top of a pump solved three critical issues facing customers: convenience, costs and reliability.
Convenience
By marrying a vertical motor with a vertical pump, the need for the mechanical gearbox, which provides the torque for a horizontal motor, is eliminated. Less equipment means easier installation and more space. Another added benefit is that a vertical motor makes the alignment of the motor shafts with the driven equipment much easier, which means less vibration.
Cost
In addition to the cost savings from fewer parts, vertical pump motors operate more efficiently-as much as 30 percent higher-than horizontal motors, because the gear box is eliminated. Vertical motors also handle more pump thrust, which eliminates the need for external thrust bearings.
Reliability
Because vertical motors are specifically designed for the pump application, they deliver better durability and reliability than their horizontal counterparts, which of course leads to greater peace of mind for the customer.
