The SRT100 actuators are based on stepper motors. Accurate and powerfull, they allow to build a 2DOF (2 actuators, pitch/roll) or 3DOF sim motion rig (3 or 4 actuators, pitch/roll/heave) for approximately 300€/actuator.
SRT100 actuators : Wiring
The wiring is quite simple. Each driver is controlled by two wires : pulse and direction. Once the driver received a “pulse” signal, the motor will moves a step. If you have three actuators instead of four, you just have to not wire the fourth motor. The “direction” signal indicates in which way the motor […]
OpenSFX actuators
OpenSFX100 actuators operate very similarly to SRT100 actuators. The difference lies mainly in the use of servo motors instead of stepper motors, which are both cheaper and less powerful.
