♦ Basic Info:
Model: IND-16GMP1625, this 16mm 12V planetary gear motor is designed for compact drive modules requiring controlled output speed and stable torque. The gearbox housing is produced by a pressure casting (die-cast) process to support rigid mounting and repeatable assembly geometry in production builds.
♦ Key Features:
♦ Alterable
Customizable items: 1. Length and shape of the shaft; 2. Voltage, output speed, torque, etc. ; 3. Adding connectors, lead wires; 4. Adding gears to shaft; 5. Adding encoder.
In a planetary gear motor, housing stiffness and alignment affect gear mesh stability and output consistency. Using a die-cast (pressure cast) gearbox housing helps maintain repeatable geometry and mounting surfaces, which is beneficial when the application has higher duty cycle or higher reaction torque.

Notes: The table lists sample builds at different rated voltages within the operating range; we can match a 12V working point by selecting the appropriate winding and ratio.
Use the gearbox sheet to select gearbox stage and ratio based on your target output speed and required torque:
Stage 1 (shortest): lower ratios (e.g., 4 / 4.75 / 6) for higher output speed and lower torque multiplication.
Stage 2: mid ratios (16 / 19 / 24 / 29 / 36) for balanced speed/torque in compact drives.
Stage 3–4: high ratios (256…509 / 542…1296) for low speed, higher torque demand applications.
For mechanisms with hard end-stops or frequent start/stop, current limiting is recommended to avoid extended operation near stall torque.

To quote the correct 16mm 12V planetary gear motor configuration quickly, please provide:
We will recommend a suitable stage/ratio and confirm a working point aligned to your load profile.
Yes. The platform supports a wide operating voltage range. The reference table lists sample configurations at different rated voltages; we can match a 12V working point by selecting the appropriate winding and gearbox ratio for your target rpm/torque.
Higher torque / lower speed applications typically use higher ratios from stage 3–4 (e.g., 256 and above). Final selection should be based on your required output speed, duty cycle, and end-stop/shock load conditions.
Common options include shaft length/style, wiring length, connector/terminal type, wire exit direction, and encoder integration evaluation. Provide your drawings and inspection checkpoints and we can align sampling and mass production builds.
