  • The flow rate from the hydraulic pump, which changes speed and friction

You should always look for high efficiency and good fuel use when you pick a motor. SHY piston motors give you high efficiency and good results, so you get more power and waste less. This means you save fuel and your machines last longer.

Tip: Always check the efficiency ratings of your motor. High efficiency means you save fuel and get more reliable power for your machines.

Power and Torque Performance

Power Output

You need to look at power output when you compare piston motors. Power output tells you how much work a motor can do in a set time. You want a motor that gives strong power without adding too much weight. The power-to-weight ratio helps you see which motor gives more power for less weight. If you choose a SHY piston motor, you get a product that gives high power and keeps weight low. This is important for machines that move, like cranes or trucks. You want your equipment to lift or move heavy loads, but you do not want extra weight slowing you down.

The power-to-weight ratio shows how much power you get for each kilogram of weight. A higher power-to-weight ratio means your machine can do more work with less weight. SHY piston motors, such as the F12 Fixed Displacement Hydraulic Piston Motor, are made to give you a high power-to-weight ratio. This helps you save fuel and makes your machine easier to handle. You also get better motor performance in both industrial and mobile jobs.

Here is a table to help you see why power-to-weight ratio matters:

0.5

Axial Piston

60

90

0.67

Note: A higher power-to-weight ratio means your machine can do more work with less weight.

Torque Characteristics

Torque tells you how much turning force a motor gives. You need to know how torque changes when the load changes. Radial piston motors work best when you need high torque at low speeds. Axial piston motors give you more speed and power when you need to move fast. The way each motor handles torque depends on the job.

  • Radial piston motors give you strong torque at low speeds.

  • Axial piston motors work better for high-speed, high-power jobs.
