TWG1220-N20VA Worm Gear Motor Self-Locking Micro Gearmotor N20 DC Motor with Right Angle Gearbox
Worm Gear Drive (90° Right Angle Output) — The input motor and output shaft are perpendicular. This unique structure allows you to mount the motor flat against a wall or inside a thin enclosure, drastically saving longitudinal space in your product design.
Inherent Self-Locking Function — A major advantage of worm gearboxes is that they prevent back-driving. Once power is cut, the output shaft remains locked in position, holding the load without needing an external brake or continuous power. This is ideal for smart locks, valves, and holding mechanisms.
Ultra-Compact & Lightweight — Weighing only 14g with a gearbox length of just 20.0 mm, it is an exceptionally compact 12x20mm drive solution.
High Rated Torque — Delivers up to 1 kg.cm rated torque and 2.0 kg.cm max momentary tolerance torque.
Smooth & Quiet Operation — The sliding contact of the worm gear provides smoother, quieter operation than traditional spur gears, with high shock load capacity.
Precision Build — Features a Φ3mm output shaft, 4-M1.6 mounting holes, and a 12x12mm gearbox frame for secure integration.
Smart Locks & Access Control — The self-locking worm gear makes it perfect for electronic door locks, deadbolts, and safe mechanisms, holding position securely without drawing power.
Automated Valves & Fluid Control — Motorized ball valves, water/gas shut-off valves, and medical micro-pumps where a 90-degree layout and holding torque are required.
Robotics & Micro Joints — Robotic arms, grippers, and humanoid robot joints where a perpendicular output saves space and self-locking prevents arm drop when powered off.
Smart Home & Automation — Automatic curtain controllers, blind adjusters, smart feeders, and camera pan/tilt mechanisms with flat mounting constraints.
Precision Instruments & Optics — Optical lens adjustment, laser focusing mechanisms, and laboratory automation equipment requiring fine, stable positioning.
Medical Devices — Portable infusion pumps, syringe drivers, and surgical instrument actuators where self-locking and compact size are critical.
Automotive Micro-Actuators — Headlight leveling, mirror folding mechanisms, and hidden door handles where a flat, right-angle drive is needed.
Vending & Dispensing Machines — Small-scale dispensing mechanisms, locking systems, and sorting equipment.
