NFP-GM37-545-EN Main Specifications
Next, the table below shows the main size, voltage, speed, power, wire, and weight data. In addition, these values help users check whether the motor fits the available space and power supply.
| Parameter | Specification |
|---|---|
| Model | NFP-GM37-545-EN |
| Shaft Diameter | 6mm |
| Shaft Length | 21mm |
| Rated Voltage | 12V / 24V DC |
| No-load Speed | 7rpm – 1,800rpm |
| No-load Current | ≤0.2A / ≤0.4A |
| Power | 19W / 80W |
| Connector | XH2.54-6Pin |
| Weight | About 290g |
As a result, the motor can meet both low-speed, high-torque needs and faster drive needs. For example, a high gear ratio gives lower speed and more torque, while a low gear ratio gives higher output speed.
12V DC 19W Gear Motor Performance
First, the 12V DC version provides no-load speeds from 7rpm to 900rpm. Also, its rated torque changes with the gear ratio, so users can select the best balance of speed and torque.
In addition, the encoder pulse count rises with the gear ratio. Therefore, high-ratio models provide more output shaft pulses per turn and allow finer speed or position control.
| Ratio | PPR | No-load Current | No-load Speed | Rated Current | Rated Speed | Rated Torque | Stall Current | Gearbox Length |
|---|---|---|---|---|---|---|---|---|
| 6.3:1 | 107.71 | ≤0.2A | 900rpm | ≤1.5A | 760rpm | 0.6kg.cm | ≤8.0A | 19.0mm |
| 10:1 | 170 | ≤0.2A | 570rpm | ≤1.5A | 480rpm | 1kg.cm | ≤8.0A | 19.0mm |
| 18.8:1 | 319.6 | ≤0.2A | 300rpm | ≤1.5A | 250rpm | 1.8kg.cm | ≤8.0A | 20.5mm |
| 30:1 | 510 | ≤0.2A | 190rpm | ≤1.5A | 160rpm | 3kg.cm | ≤8.0A | 21.5mm |
| 50:1 | 850 | ≤0.2A | 112rpm | ≤1.5A | 95rpm | 4.8kg.cm | ≤8.0A | 24.0mm |
| 90:1 | 1,530 | ≤0.2A | 62rpm | ≤1.5A | 52rpm | 8.5kg.cm | ≤8.0A | 24.0mm |
| 150:1 | 2,550 | ≤0.2A | 38rpm | ≤1.5A | 32rpm | 14.5kg.cm | ≤8.0A | 26.5mm |
| 270:1 | 4,590 | ≤0.2A | 21rpm | ≤1.5A | 15rpm | ≤35.0kg.cm | ≤8.0A | 26.5mm |
| 450:1 | 7,650 | ≤0.2A | 12rpm | ≤1.5A | 10rpm | ≤35.0kg.cm | ≤8.0A | 29.0mm |
| 650:1 | 10,710 | ≤0.2A | 8.8rpm | ≤1.5A | 7rpm | ≤35.0kg.cm | ≤8.0A | 29.0mm |
| 810:1 | 13,770 | ≤0.2A | 7rpm | ≤1.5A | 6rpm | ≤35.0kg.cm | ≤8.0A | 29.0mm |
As a result, the 12V model covers a wide range of speed and torque needs. For example, the 6.3:1 option gives 900rpm no-load speed, while the 810:1 option gives 7rpm no-load speed.
Also, all reduced no-load speeds have a tolerance of ±15%. Therefore, the actual speed may change because of load, voltage, temperature, and normal production tolerance.
24V DC 80W Gear Motor Performance
Next, the 24V DC version provides more power and higher speed. Moreover, it supports no-load speeds from 14rpm to 1,800rpm for both fast motion and high-torque drive systems.
Similarly, the motor uses the same wide gear ratio range. Therefore, users can select a suitable option without changing the basic motor size or encoder system.
| Ratio | PPR | No-load Current | No-load Speed | Rated Current | Rated Speed | Rated Torque | Stall Current | Gearbox Length |
|---|---|---|---|---|---|---|---|---|
| 6.3:1 | 107.71 | ≤0.4A | 1,800rpm | ≤2.3A | 1,500rpm | 1kg.cm | ≤15.0A | 19.0mm |
| 10:1 | 170 | ≤0.4A | 1,150rpm | ≤2.3A | 950rpm | 1.8kg.cm | ≤15.0A | 19.0mm |
| 18.8:1 | 319.6 | ≤0.4A | 610rpm | ≤2.3A | 510rpm | 3.5kg.cm | ≤15.0A | 20.5mm |
| 30:1 | 510 | ≤0.4A | 380rpm | ≤2.3A | 325rpm | 5.5kg.cm | ≤15.0A | 21.5mm |
| 50:1 | 850 | ≤0.4A | 225rpm | ≤2.3A | 195rpm | 9kg.cm | ≤15.0A | 24.0mm |
| 90:1 | 1,530 | ≤0.4A | 125rpm | ≤2.3A | 105rpm | 16kg.cm | ≤15.0A | 24.0mm |
| 150:1 | 2,550 | ≤0.4A | 75rpm | ≤2.3A | 65rpm | ≤35.0kg.cm | ≤15.0A | 26.5mm |
| 270:1 | 4,590 | ≤0.4A | 42rpm | ≤2.3A | 38rpm | ≤35.0kg.cm | ≤15.0A | 26.5mm |
| 450:1 | 7,650 | ≤0.4A | 25rpm | ≤2.3A | 23rpm | ≤35.0kg.cm | ≤15.0A | 29.0mm |
| 650:1 | 10,710 | ≤0.4A | 17rpm | ≤2.3A | 15rpm | ≤35.0kg.cm | ≤15.0A | 29.0mm |
| 810:1 | 13,770 | ≤0.4A | 14rpm | ≤2.3A | 13rpm | ≤35.0kg.cm | ≤15.0A | 29.0mm |
As a result, the 24V model gives higher output speed than the 12V model at the same ratio. For example, the 10:1 version provides 1,150rpm no-load speed and 950rpm rated speed.
Also, all reduced no-load speeds have a tolerance of ±15%. Therefore, users should allow for normal speed change during system design and testing.
37mm Gear Motor Outline Drawing
First, the outline drawing below shows the motor body, gearbox, output shaft, mounting holes, and encoder cover. Therefore, engineers can check the available space before adding the motor to a machine or device.
In addition, the gearbox length changes with the selected ratio. As a result, users should check the gearbox length in the performance table before they confirm the final mounting space.
Miniature Geared Motor Encoder Connection
Next, the motor includes an AB dual-phase incremental magnetic Hall encoder. Also, the encoder can send speed and direction signals to a microcontroller, PLC, or motor control board.
Furthermore, the encoder supports both 3.3V and 5V DC power. Therefore, it can connect to many common control systems without a complex signal board.
Hall Encoder Specifications
First, review the encoder data before wiring the motor. In addition, make sure the power, ground, Hall A, and Hall B wires are connected to the correct controller pins.
| Parameter | AB Dual-phase Incremental Magnetic Hall Encoder |
|---|---|
| Output Pulse Count | Basic pulse count of 17 PPR × gear reduction ratio |
| Supply Voltage | 3.3V / 5.0V DC |
| Basic Function | Built-in pull-up and signal-shaping resistor for direct MCU connection |
| Interface Type | XH2.54-6Pin with standard connecting cable |
| Output Signal Type | Square-wave AB-phase signal |
| Response Frequency | 100kHz |
| Basic Pulse Count | 17 PPR |
| Magnetic Ring Poles | 34 poles, or 17 pole pairs |
As a result, the encoder can help measure speed, direction, travel distance, and shaft position. For example, a controller can compare target speed with actual speed and then adjust motor power.
Moreover, the AB signal can show the rotation direction. Therefore, the motor is suitable for closed-loop control, accurate movement, and repeatable positioning.

Need a more durable metal gear motor to replace the original plastic motor. 24v is exactly what the electric wheeler wants, looking forward to the change.

The metal gear motor is great. I get ~110rpm, is quieter than I thought it would be, and has more torque. It makes my projects move. So much fun.🤔
