N20 Offset Spur Gear Motor

♦ Basic Info:

Model: IND-24GMN20

Diameter: 24mm

Body Length: 19mm

Operating Voltage: 2V DC-14V DC

♦ Key Features

  1. Offset shaft (packaging fix):
    Off‑center output lets you route the motor around brackets/walls and still hit your gear/linkage centerline—often avoiding bracket redesign or extra idlers compared with an inline N20.
  2. BOM/PO friendly configuration:
    Define gear ratio + winding/voltage (2–14V) + your loaded RPM/torque target + interfaces (shaft spec, leads/connector, optional encoder). Once frozen, it’s a repeatable, controllable build for production.
  3.  Ratio choices for real loads:
    Multiple ratio choices (e.g., 50/100/298/500) help you land the right speed‑vs‑torque point for mechanisms with load spikes/hard-stops (smart locks, robots, coffee machines, compact actuators), focusing on loaded performance and stall margin—not just no‑load RPM.

Product Introduction

Meet our IND-24GMN20 N20 offset spur gear motor—a compact micro DC geared motor built for projects where an inline shaft makes packaging awkward. The non-concentric (offset) output lets you route the motor body around ribs, brackets, and housings, or align to a gear train without redesigning your whole layout—exactly why many engineers choose offset/parallel-shaft gearboxes in tight assemblies.

For sourcing and design reviews, the key points are straightforward: 2–14V DC operating range, multiple gear ratios, and a configuration process that’s easy to lock down on a purchase order. Sample builds include 50:1, 100:1, 298:1, and 500:1, covering the common “faster output vs. higher torque/holding” trade-off buyers compare across suppliers. If you need a specific working point, we can tune ratio, winding, speed/torque target, plus the mechanical interface—shaft length/shape, coupler features, and connector/lead wire options. An encoder can also be added when you need feedback for positioning or stall detection.

This model is a practical fit for smart locks, coffee machines, small robots, and compact actuators, where real loads fluctuate and hard-stops can happen.

Still deciding whether N20 is enough margin or you should step up in body length? Use our N20 vs N30 gear motor spec guide to compare torque headroom, driver sizing, and integration risks before you release a PO.

FAQ for N20 Offset Spur Gear Motor (IND-24GMN20)

 

Q1. What is an “offset shaft” N20 spur gear motor, and why choose it over a standard inline N20 gear motor?

An offset-shaft (off-center output) gearbox makes mechanical packaging much easier in tight assemblies. It helps you clear ribs/brackets/walls and align to gears, linkages, or cams without redesigning the whole layout just to keep the output shaft on the centerline. This is especially useful for compact mechanisms like smart locks, small robots, coffee machines, and mini actuators.

Q2. What is the operating voltage range? Can I run it on 3V / 5V / 6V / 12V?

This model supports a wide 2–14V DC operating range, but the best match depends on the chosen gear ratio and motor winding (the table on the page shows sample configurations). In practice, if you plan to use 3V / 5V / 6V / 12V, you should confirm your target output speed (RPM), required torque, duty cycle, and stall risk—then select the gear ratio/winding accordingly to avoid overcurrent or insufficient torque.

Q3. How do I choose the gear ratio (50:1 / 100:1 / 298:1 / 500:1)?

Gear ratio is mainly a trade-off between speed and torque:

  • Higher ratio (e.g., 298:1, 500:1) → lower output RPM, higher output torque/holding capability; better for load spikes and hard-stops (common in smart locks and actuators).
  • Lower ratio (e.g., 50:1, 100:1) → higher output RPM; better when speed is more important than torque.
    If you share your target RPM and estimated load torque, you can narrow down the ratio quickly.

Q4. How do I prevent damage from stall or hard-stop conditions (common in locks/actuators)?

Stall (locked rotor) can cause high current and heat in micro DC gearmotors. Recommended protections include:

  • Use a driver/control strategy with current limiting and stall detection (current threshold + time threshold).
  • Design with torque margin and avoid long-duration stall.
  • If you need feedback, consider a version with an encoder for motion/position monitoring and abnormal-stop detection.
