A hollow shaft motor is a type of electric motor characterized by a central opening or bore running through its rotor shaft. This design allows for the passage of various components, such as cables, hoses, or pump shafts, directly through the motors shaft. Its particularly useful in applications where a compact and efficient direct drive system is required, as it eliminates the need for couplings and the alignment issues that come with conventional motor-pump sets. Hollow shaft motors are known for their durability, reliability, and ease of use, making them a preferred choice in vertical turbine pump industries and other applications requiring such configurations
