Hydraulic Actuators and Control Components - Hydraulics and Pneumatics

Like in hydraulic pumps, the performance of hydraulic motor is also evaluated by using volumetric, mechanical, and overall efficiencies.

HYDRAULIC MOTOR PERFORMANCE

Like in hydraulic pumps, the performance of hydraulic motor is also evaluated by using volumetric, mechanical, and overall efficiencies.

1. Volumetric Efficiency (ηvol)

The volumetric efficiency of a hydraulic motor is the inverse of that for a pump. Mathematically,


2. Mechanical Efficiency (ηmech)

The mechanical efficiency of a hydraulic motor is the inverse of that for a pump.

Mathematically,


3. Overall Efficiency (ηo)

The overall efficiency of the hydraulic motor is the product of the volumetric and mechanical efficiencies.

Mathematically,


Combining equations (5.11), (5.12), (5.13), and (5.14), we get


Note 

The actual power delivered to a motor by the fluid is called by the term 'hydraulic power'. Similarly, the actual power delivered to a load by a motor via a rotating shaft is called ‘brake power'.
