II. Core Performance Parameters by Operating Voltage
1. DC 12V Operation (Max Power: 2.3W)
| Gear Ratio | No-load Speed (rpm) | Rated Speed (rpm) | Rated Torque (Kg·cm) | Stall Torque (Kg·cm) | No-load Current (mA) | Rated Current (A) | Stall Current (A) |
|---|---|---|---|---|---|---|---|
| 1:20 | 320 | 200 | 1.00 | ≥2.5 | ≤65 | ≤0.7 | ≤1.7 |
| 1:90 | 72 | 50 | 4.00 | ≥11 | ≤65 | ≤0.5 | ≤1.7 |
| 1:225 | 28 | 20 | 9.50 | ≥30 | ≤65 | ≤0.5 | ≤1.7 |
| 1:453 | 14 | 9 | 15.00 | ≥30 | ≤65 | ≤0.5 | ≤1.7 |
2. DC 6V Operation (Max Power: 0.6W)
| Gear Ratio | No-load Speed (rpm) | Rated Speed (rpm) | Rated Torque (Kg·cm) | Stall Torque (Kg·cm) | No-load Current (mA) | Rated Current (A) | Stall Current (A) |
|---|---|---|---|---|---|---|---|
| 1:20 | 160 | 100 | 0.45 | ≥1.2 | ≤45 | ≤0.35 | ≤0.85 |
| 1:90 | 36 | 25 | 2.00 | ≥5 | ≤45 | ≤0.35 | ≤0.85 |
| 1:225 | 14 | 10 | 5.00 | ≥15 | ≤45 | ≤0.35 | ≤0.85 |
| 1:453 | 7 | 5 | 10.00 | ≥30 | ≤45 | ≤0.35 | ≤0.85 |
III. Available Configuration Options
- Bare Motor: Only the motor itself, for users who already have a compatible power supply and drive/speed controller.
- Motor + Pre-wired Leads: Pre-assembled with crimped leads for direct connection to a power supply, suitable for simple on/off control scenarios.
- Motor + Basic Speed Controller: Supports manual speed adjustment, ideal for applications requiring variable speed control.
- Motor + Forward/Reverse Speed Controller: Supports both forward/reverse rotation and speed control, perfect for bidirectional mechanisms (e.g., trash can/toilet lid opening/closing).
- Motor + 12V Power Supply + F/R Speed Controller: Complete plug-and-play kit, no additional accessories required.
IV. Critical Usage Notes (Important Warnings)
- No Overload / Stall Operation: Damage caused by stalling or exceeding the maximum load limit is not covered under warranty. Prolonged stalling will burn the motor windings.
- Voltage Matching: Always use a power supply matching the rated voltage. Overvoltage will damage the motor; undervoltage will cause insufficient torque and abnormal speed.
- Torque-Oriented Selection: Always select the motor based on the rated torque, and avoid continuous overloading, which can shorten lifespan or damage internal gears.
- Speed Reduction Reduces Torque: Lowering the motor speed will directly reduce output torque. Evaluate your application's torque requirements before implementing speed control.
- Normal Operating Noise: Minor fluctuations in operating noise (dB) due to changes in speed and load are normal and do not indicate a fault.
V. Selection & Application Recommendations
- High Torque, Low Speed: Choose the 12V-14rpm-453:1 (12V, 1:453) variant, with a rated torque of 15 Kg·cm, suitable for heavy-load applications.
- Low-Power, Battery-Powered Use: Consider the 6V variants, which offer lower current draw, ideal for light-load, battery-operated devices.
- Beginner / Plug-and-Play Use: The Motor + 12V Power Supply + F/R Speed Controller kit is recommended for immediate use without additional setup.
