Description Compact size, high torque Self-locking Magnetic encoder, 2 channels, 11PPR RoHS compliantThis is a DC motor and worm gearbox combination, both 12V and 24V motor options are available. The first gearbox stage is a worm-and-wheel, meaning that the transmission cannot be back-driven once in position. The gearbox is very sturdy, both outside and in, with larger-pitch gears than found in cheap gearboxes of a similar size, allowing it to transfer and support higher torque loads without the gear teeth breaking. An 8mm diameter output shaft with dual ball-bearing support means that relatively large loads can be mounted directly to the output shaft.This motor, with both 12V and 24V options and a hall sensor encoder, provides an ideal solution for applications requiring a high output torque from a compact device. The right-angle gearbox also enables the motor to fit into positions that planetary and conventional spur gear motors wouldn't be able to.Special effects, DIY, robotics and automation projects can all benefit from the steady output speed and the resistance to being rotated (self-locking property) which is provided by the worm-and-wheel stage once the motor is in a position. The 8mm output shaft and output gear stage are much stronger than that of similar motors on the market, meaning that larger radial loads can be supported without causing damage to the gearbox.View moreDimensionsGear box : 58L X 40W X 26.8H mmMotor : 36D X 75L mmShaft : 8D X 15L mm, D-shapedLinksAttached files encoder.pdf 5840WG-555PM-EN motor.pdfSpecificationsModel: 5840WG-555PM-280-EN 12VGear ratio : 1/280No Load Current: < 500 mANo Load Speed : 28 RPMRated Torque : 70 Kg.cmRated Speed : 19 RPMRated Current : < 3.9 AStall Current : < 13 AStall Torque : 70 Kg.cm
