Description: 12V Linear Actuators DC 12V 20mm/s Speed 100mm Stroke 100N 10KG Load Waterproof Electric Small Linear Actuator For Electric Bicycle
These low-cost linear actuators are 12V DC gearmotors that use a worm drive to move a shaft back and forth along its length. The worm drive ensures that the shaft will hold its position even when unpowered. Two limit switches safely stop the motor at either end of its range, while diodes allow it to reverse direction after reaching a limit point. The actuators are mostly metal, and the entire case is sealed to protect against dust and water (rated IP54).
The linear actuators are available in a variety of lengths and with optional potentiometers that are linked to the shaft position, for use in feedback systems. They are also available in two speeds: 0.6″/s (16 mm/s) and 1.5″/s (40 mm/s). The slower 0.6″/s versions can exert a maximum force of about 110 lbs (500 N or 51 kg), while the faster 1.5″/s versions can exert up to 22 lbs (100 N or 10 kg).
You can use the table on our linear actuator category page to help you find the actuator with the combination of speed and force that best meets your project’s requirements.
Mounting brackets are available for attaching the actuators to a structure; two are required for each actuator.
Using the actuator:
To test-drive the actuator, simply connect a power source of up to 12 V to the motor leads. Reversing the applied voltage will reverse the direction of motion. A motor controller or motor driver is required for electronic speed and direction control. We recommend our Jrk Motor Controllers for use with the feedback actuators and the Pololu Simple Motor Controller 18v7 for controlling the actuators without feedback, though many of our other motor controllers and motor drivers are capable of powering this actuator.
These actuators have a stall current of 7 A at 12 V, but they will, on average, draw far less than this when used within their load ratings. They draw around 1 A with no load and approximately 3 A at their maximum rated load, so we have found they generally work well with our lower-power jrk 21v3 motor controller with feedback (see the bottom of this page for more information using this controller for closed-loop linear actuator position control). Note, however, that the actuators can briefly draw close to their full stall current when abruptly started or on a sudden change of direction. Such current spikes can be dampened if you take steps to limit the acceleration of the actuator (many of our motor controllers offer optional acceleration limiting).
