Choosing Electric Actuators and Controllers: What to Consider
When selecting electric actuators and controllers, it is crucial to consider a range of criteria, encompassing both mechanical and electronic aspects.
1. Application Data:
The selection of an electric actuator is contingent upon process conditions and the specific application. Consider the following factors:
- Workload
- Stroke
- Speed
- Actuation method
- Intermediate stop locations
- Installation space
- Control approach
- Encoder type
- Load arrangement in relation to the actuator
- Application orientation: horizontal, vertical, or wall
- Cycle time, influencing speed and acceleration
Additionally, other requirements such as electrical connection type, environmental considerations (dust resistance, water-jet protection, secondary battery compatibility), installation expansion plans, and additional accessories should be taken into account.
2. Selection of Mechanics:
Mechanical Transmission System:
The choice of the mechanical system significantly influences the precision and dynamism of the overall system. Two main types of mechanical transmission systems are available:
- Spindle: These systems offer high precision and require minimal maintenance but may not be suitable for long strokes.
- Belt: The belt transmission system is well-suited for longer strokes, although it comes with a trade-off of lower thrust force.
The guidance system is a critical criterion as it determines the longevity and robustness of the electric actuator. Various guidance types include:
- Skate with recirculating ball system
- Double guide systems
- Auxiliary guides for system reinforcement
3. Motor Selection:
Motor Type
The choice of motor, whether stepper motor or servo motor, plays a crucial role in determining the dynamism of the system.
- Stepper Motors: Industrial stepper motors offer an economical solution, providing high repeatability and increased torque at lower revolutions, making them well-suited for applications such as handling and pick & place.
- Servomotors: Industrial servomotors boast high power and dynamics, making them suitable for applications requiring coordinated movements.
Type of Encoder Integrated into the Motor
Properly selecting the encoder is vital as it provides real-time and immediate information about the electric cylinder's status. There are three main types of encoders:
- Incremental Encoder
- Absolute Encoder
- Absolute Encoder without Battery
Control Type:
In conjunction with the actuator, it is essential to choose a controller that aligns with the application's requirements.
There are three primary groups of controllers:
- Positioner Controller
- Pulse Controller
- Fieldbus Controller
Furthermore, each of these controller types can be either single-axis or multi-axis.
