Product Introduction 

The IND-12GMWN20 is an N20-size micro worm gear motor built around a 90‑degree worm gearhead for mechanisms that need a right-angle output and controlled low-speed motion. Instead of selecting by “high torque” claims, this platform is intended to be specified by measurable constraints: installation envelope, supply rail, target output speed, and allowable peak current.

For mechanical fit, the motor is Ø12 mm with a 15 mm body length, and it operates across a 5–14 V DC range. For electrical planning, the reference configurations on the page provide current figures that matter to buyers: typical no‑load current is in the 30–35 mA range at rated voltage, while stall current is around 540–580 mA depending on ratio. These values are directly usable for selecting an H‑bridge driver, wire gauge, connector rating, and battery peak-current budget.

The worm gearbox ratios cover 59:1 to 1168:1 (gearbox length 18 mm), which allows you to position your design at the required output RPM without running the motor outside its efficient region. Two reference load points are listed: a 300:1 configuration at 6 V and a 1168:1 configuration at 12 V, showing on‑load speeds from approximately 8–20 rpm with corresponding torque data. This makes it easier to freeze a purchase specification and reduce trial builds.

N20 worm gearbox motors are often selected for smart lock modules, micro valve actuation, and compact robotic mechanisms where reverse-driving resistance is desired. Because holding behavior can change under vibration and shock, we recommend confirming reverse torque requirements and duty cycle before finalizing the ratio. OEM customization includes shaft length/shape, voltage/winding selection, lead wires/connectors, and optional encoder integration.

FAQs

Q1: What is the voltage range for this N20 micro worm gear motor?

The IND-12GMWN20 is designed for 5–14V DC systems. Common builds are aligned to 6V or 12V depending on the required speed/torque point and your driver/battery design.

Q2: Is an N20 worm gearbox motor self-locking for smart lock or valve applications?

Worm gearheads typically provide back-drive resistance, which helps with position holding in smart lock actuators and micro valve actuators. Final holding torque depends on ratio, lubrication, and shock/vibration—share your reverse torque requirement to confirm.

Q3: Can I add an encoder to an N20 90-degree worm gear motor?

Yes. We can add an encoder (Hall/magnetic options depending on configuration) and customize lead wires/connectors. This is commonly used for closed-loop speed control or position verification in small robotics and security devices.
