In physical terms, a motor is something that converts energy into moving parts of a machine. These machines can be cars or printers. If the motor no longer rotates at the same moment, then the world will become unimaginable.
In modern society, motors are ubiquitous. Over the centuries, engineers have produced many different types of motors.
Many motors are actuators, which means that they produce motion through the application of torque. For a long time, the hydraulic driving force of hydraulic actuators was the standard at the time. However, in the 21st century, with the advancement of electric drives, coupled with the fact that electric power has become very sufficient and easy to control, this type of motor is increasing. Of the two, is one better than the other? It depends on the situation.
Overview of Hydraulic System
If you have used floor jacks, or have driven vehicles with power brakes or power steering, you may be surprised that you can move such a large number of objects without using a lot of effort. (On the other hand, you can have been consumed by the task of changing tires on the side of the road so much energy to consider these ideas.)
Through the use of hydraulic systems, these tasks and similar tasks become more possible. The hydraulic system does not create power, but on the contrary, it transforms it into the required form from an external source.
The research of hydraulics includes two main areas. Hydraulics is the use of liquids to do work at high flow and low pressure. "Old-fashioned" mills use energy from water streams to grind grain. On the contrary, hydrostatics uses the high pressure and low fluidity of water to do work. In the language of physics, what is the basis of this trade-off?
Advantages of hydraulic motors
The main advantage of hydraulic motors is that they can be used to generate great force.
Hydraulic motors use incompressible liquids, which allows tighter control of the motors, and therefore higher accuracy during movement. Among heavy mobile equipment, they are very useful.
The advantages of motors
The opening of the hydraulic motor is not very fast, the motor is very fast (at most 10m/s). They have programmable speed and stop position, unlike hydraulic motors, which can provide high precision positioning required. Electronic sensors can provide precise feedback with the force applied during movement.
