What Are The Advantages Of Hydraulic Motors Compared With Electric Motors

Advantages of hydraulic motors over electric motors include:
1. High bearing capacity
The hydraulic motor has a very high carrying capacity and can withstand up to 1000 times the starting torque under extreme conditions. This makes them very useful in heavy-duty and high-load applications small hydraulic walking motors.
2. High reliability
Because hydraulic motors have no electrical parts, they are more resistant to high temperature, vibration, humidity and other conditions than electric motors, so they are more reliable in harsh working environments.
3. Easy to control
The control mode of hydraulic motor is realized by adjusting the input flow, which has very good control performance. In high speed, high torque and positive and negative rotation can show very good performance.
4. Easy maintenance
Hydraulic motor structure is relatively simple, relatively easy to maintain. When changing materials or upgrading the hydraulic system, it can be done without a major change.
However, hydraulic motors also have some disadvantages:
1. Energy efficiency is relatively low
Hydraulic motors rely mainly on high-pressure fluids to work, which can lead to energy loss and make them less energy efficient than electric motors.
2. Loud noise
Because the liquid in the hydraulic system needs to be driven by high pressure pump, so the hydraulic motor will produce certain noise when running, which seriously affects the working environment and the health of the staff.
3. High maintenance cost
Although hydraulic motors have high reliability, if liquid leakage or other parts are damaged, the repair cost will be higher than the torque hydraulic motors.
To sum up, the application scope of hydraulic motors is relatively specialized and high cost, they are generally used in the need to withstand high pressure, high load and high precision requirements, such as heavy industry, mining, aviation and military fields. Electric motors are more suitable for general industry, daily life and electronic equipment, with a wider range of applications.
