Recommended add-ons
Motion component categories
Linear Motion
- Electric linear actuators
- Lead screws & nuts
- Linear rails, rods & carriages
Ideal for Z-axes, sliders, lifts and precision positioning.
Rotary Actuators
- Stepper motors (NEMA-class, geared)
- DC gear motors
- High-torque servos
Great for CNC axes, wheels, joints, grippers and turrets.
On/Off Actuation
- Solenoids & push-pull actuators
- Door latches & valve actuators
For locks, gates, triggers and fast “bang-bang” motion.
Mechanical Transmission
- Flexible & rigid couplers
- Timing pulleys & gears
- Brackets & mounting hardware
Connect shafts, motors and loads with minimal backlash.
Feedback & Limits
- Limit switches / endstops
- Encoders & hall sensors
Keep axes homed, safe and repeatable.
Control Electronics
The brains that turn pulses into smooth motion.
Chooser guide: which actuator should I use?
| Application | Recommended actuator | Notes |
|---|---|---|
| CNC / 3D printer axis | Stepper motor + lead screw / belt | Steppers give precise, repeatable steps; pair with proper driver and microstepping. |
| Robot joint / pan-tilt | Servo motor or geared DC + encoder | Servos are easy with PWM; use geared DC + feedback for higher torque or custom ranges. |
| Linear push / lift | Linear actuator or lead screw + stepper | Choose based on required stroke, speed and load (kg / N). |
| Quick lock / trigger | Solenoid actuator | Good for short pulses; always observe duty cycle and drive with a proper transistor/relay. |
| Slow, high-force positioning | Geared DC motor + lead screw | High torque at low speed, ideal for heavy lifts with limit switches. |
Always check rated voltage, current, torque/force, speed and duty cycle. Oversize your power supply and drivers for safety margin.
Starter build ideas
- Mini CNC platform: NEMA steppers + lead screws/rails + stepper drivers + limit switches + Arduino.
- Sliding camera rig: Linear rail + stepper + coupler + TMC/A4988 module + joystick or keypad control.
- Smart door / gate: Linear actuator or geared DC motor + relay module + limit switches + ESP32 Wi-Fi control.
FAQ
How do I size a motor or actuator for my project?
Estimate the load (kg / N), travel speed and duty cycle. Then pick a motor or actuator whose rated torque/force and current are comfortably above your requirement—ideally with 20–30% headroom.
What driver do I need for my stepper motor?
Match the driver to the motor’s rated current and supply voltage. Common choices are A4988/DRV8825 for small NEMA steppers, or higher-current drivers for bigger CNC axes.
Can I run these from Arduino, ESP32 or Raspberry Pi?
Yes. Use a dedicated motor/stepper driver between the MCU and the actuator. Never drive motors directly from GPIO pins.
Do you ship nationwide?
Yes—fast shipping anywhere in the Philippines. Same-day processing on in-stock orders before cutoff.
