The 5 most important reasons to choose direct drive air motors:
Direct drive air motors are a type of motor that can be used for controlled movement, positioning, and indexing. They offer several advantages over other types of motors, including:
- High precision: Direct drive air motors are capable of very precise movements, making them ideal for applications that require high accuracy and repeatability.
- Low maintenance: Since direct drive air motors have fewer moving parts than other types of motors, they require less maintenance and are less prone to wear and tear.
- High torque: Direct drive air motors can produce high torque at low speeds, which makes them ideal for applications that require high force. Since there is no gear assembly attached, there is less inertia and excellent starting torque.
- Fast acceleration: Direct drive air motor can accelerate quickly, which makes them ideal for applications that require fast movement.
- Low noise: Direct drive air motor are relatively quiet compared to other types of motor, which makes them ideal for applications where noise is a concern.
Overall, direct drive air motor are a great choice for applications that require high precision, low maintenance, high torque, fast acceleration, and low noise. They are commonly used in industries such as manufacturing, robotics, and automation.
There are several types of direct drive air motors, including vane, piston, and turbine motors . Each type has its own unique design and working principle. Here is a brief overview of the differences between these types:
- Vane motors: Vane motors are the most commonly used type of direct drive air motor. They are produced with power ratings up to approximately 5 kW . The design of a vane motor consists of a slotted rotor that rotates eccentrically in the chamber formed by the cylinder and cylinder end plates .
- Piston motors: Piston motors are capable of producing high torque and are ideal for applications that require high force . The design of a piston motor consists of a piston that moves back and forth in a cylinder .
- Turbine motors: Turbine motors are capable of producing high speeds and are ideal for applications that require fast movement . The design of a turbine motor consists of a rotor with blades that rotates in a housing . Turbine motor are seldomly selected for precise movement due to its incredibly high speed (up to 50000 + rpm) and the fact that it’s not reversable. It is only mentioned here as it is an alternative that could work in some applications. Options 1 and 3 are much better suited for indexing and positioning in general.
