General Motor Data
First, the table below shows the main motor data. Also, it helps users compare voltage, speed, current, torque, shaft size, rotation, life, and weight.
Therefore, users can check the basic motor limits before selecting a gearbox ratio. In addition, the data helps match the motor to the available power supply and load.
| Model | NFP-GM37-550CS |
|---|---|
| Rated Voltage | 12V / 24V DC |
| No-load Speed | 40rpm–650rpm |
| No-load Current | ≤0.45A / ≤0.6A |
| Max Torque | 30kg.cm |
| Shaft Diameter | 6mm |
| Shaft Length | 21mm |
| Rotation | CW / CCW |
| Lifetime | ≥800h |
| Weight | Approx. 300g |
As a result, this model offers strong torque in one compact gear motor body. Moreover, the 6mm shaft can connect to wheels, gears, arms, and other drive parts.
Model: NFP-GM37-550CS, 12V DC
First, the 12V DC version is suitable for compact 12V drive systems. Also, the table below compares ratio, gearbox length, current, speed, torque, and stall data.
Therefore, a lower ratio gives higher output speed. In addition, a higher ratio gives lower speed and stronger output torque.
| Ratio | Gearbox Length | No-load Current | No-load Speed | Rated Current | Rated Speed | Rated Torque | Stall Current | Stall Torque |
|---|---|---|---|---|---|---|---|---|
| 22.6:1 | 24.7mm | ≤0.45A | 325rpm | ≤2A | 275rpm | 4kg.cm | ≤13A | ≥20kg.cm |
| 53:1 | 27.2mm | ≤0.45A | 135rpm | ≤2A | 115rpm | 10kg.cm | ≤13A | ≤30kg.cm |
| 77:1 | 27.2mm | ≤0.45A | 95rpm | ≤2A | 80rpm | 14kg.cm | ≤13A | ≤30kg.cm |
Note: All reduced no-load speeds have a tolerance of ±15%.
As a result, the 12V version covers no-load speeds from 95rpm to 325rpm. Moreover, the 77:1 ratio gives the highest rated torque in this table.
For example, the 22.6:1 ratio is a better choice when higher speed is more important. Similarly, the 77:1 ratio is useful when the load needs more torque at a lower speed.
Model: NFP-GM37-550CS, 24V DC
Next, the 24V DC version gives higher speed and stronger output than the 12V version. Also, it is suitable for 24V systems that need more drive power.
Therefore, users can select this version for heavier drive tasks. In addition, the higher ratios support lower speed and higher torque.
| Ratio | Gearbox Length | No-load Current | No-load Speed | Rated Current | Rated Speed | Rated Torque | Stall Current | Stall Torque |
|---|---|---|---|---|---|---|---|---|
| 22.6:1 | 24.7mm | ≤0.6A | 650rpm | ≤4A | 550rpm | 8kg.cm | ≤26A | ≤30kg.cm |
| 53:1 | 27.2mm | ≤0.6A | 270rpm | ≤4A | 230rpm | 20kg.cm | ≤26A | ≤30kg.cm |
| 77:1 | 27.2mm | ≤0.6A | 190rpm | ≤4A | 160rpm | 25kg.cm | ≤26A | ≤30kg.cm |
Note: All reduced no-load speeds have a tolerance of ±15%.
In conclusion, the 24V version covers no-load speeds from 190rpm to 650rpm. Also, the 77:1 ratio gives the highest rated torque for heavy drive tasks.
For example, the 22.6:1 ratio supports faster movement at 650rpm. In contrast, the 77:1 ratio lowers the speed to 190rpm and raises the rated torque to 25kg.cm.
High-Torque Spur Gear Motor Dimensions
First, the outline drawing helps users check motor size, gearbox length, shaft size, and mounting space. Therefore, it is useful before sample tests and product design.
In addition, the working principle of this DC gear motor is simple. The RS-550 motor creates drive power, while the gears lower speed and raise output force.
Moreover, the metal gear system supports stable motion under load. As a result, the motor can work well in machines that need low speed and high torque.
Outline Drawing and Design Benefits
- Center output shaft: Helps connect drive parts in a stable way.
- High torque: The gearbox raises output force for heavier loads.
- 12V and 24V options: Supports different DC power systems.
- Compact gearhead: Saves space in small machines and devices.
- Long lifetime: Supports a service life of at least 800h under suitable use.
Also, the image below shows the main outline dimensions of the motor and gearbox. Therefore, users can check the available mounting space before building a sample.
