Note: All reduced no-load speeds have a tolerance of ±15%.

As a result, the 6V version covers speeds from 10rpm to 760rpm. Moreover, the 450:1 ratio gives the strongest rated torque in this table.

12V DC Performance Data

Next, the table below shows the 12V DC version. In addition, this version provides higher speed than the 6V version.

Moreover, the 12V version is useful for systems that need stronger output and higher rated current capacity. Therefore, it fits many robot and smart device projects.

Model: NFP-GM37-520-PEN, 12V DC

Note: All reduced no-load speeds have a tolerance of ±15%.

In short, the 12V version covers speeds from 21rpm to 1530rpm. Also, the high-ratio options provide stronger torque for slow drive tasks.

24V DC Performance Data

Finally, the table below shows the 24V DC version. In addition, this version keeps high speed while using lower rated current than the 12V version in many ratios.

As a result, users can choose it for 24V control systems. Moreover, it is suitable for compact equipment that needs stable speed feedback.

Model: NFP-GM37-520-PEN, 24V DC

Note: All reduced no-load speeds have a tolerance of ±15%.

In conclusion, the 24V version covers speeds from 21rpm to 1530rpm. Therefore, it is a good choice for 24V products that need speed feedback and stable torque.

Selection Notes

First, users should choose the voltage and gear ratio based on load, speed, and control needs. Also, users should confirm the encoder interface before wiring.

• First, for higher speed: Choose a lower gear ratio. Therefore, the output speed will be higher.
• In addition, for higher torque: Choose a higher gear ratio. As a result, the output speed will be lower, but torque will increase.
• Also, for 6V systems: Choose the 6V version when the driver and power supply use 6V DC.
• Next, for 12V systems: Choose the 12V version when the driver and power supply use 12V DC.
• Moreover, for 24V systems: Choose the 24V version when the driver and power supply use 24V DC.
• Finally, for encoder use: Use an MCU with a hardware encoder interface. Moreover, do not reverse VCC and GND.

In short, the NFP-GM37-520-PEN DC gear motor with photoelectric encoder is a good fit for products that need 6V, 12V, or 24V DC power, pure copper winding, encoder feedback, 37mm gearbox, and stable low-speed torque.
