How to design Gear Motor for Automatic Baby Cradle Kit
When designing a gear motor for an automatic baby cradle kit, we focus on 4 key requirements.
1. Torque and Rpm
The weight of a baby cradle does not exceed 15kg, so there is no particularly high requirement for the torque of the motor.
For the application of baby cradles, the motor needs to provide a lower speed.
Recommend Model
Motor Model | Voltage (V) | Current (A) | Input Power (W) | Torque (N.m) | Speed (rpm) | Output Power (W) | Efficiency (%) |
---|---|---|---|---|---|---|---|
GR-37125000-90K | 12.0 | 0.457 | 5.482 | 0.484 | 37.34 | 1.893 | 34.5 |
GR-37127000-60K | 12.0 | 0.705 | 8.460 | 0.322 | 90.43 | 3.051 | 36.1 |
2. Noise Control
Motor noise must be extremely low to avoid disturbing the baby’s sleep. To achieve this, we use:
- Low-speed DC Brush motors to minimize operational noise
- High-precision spur gearboxes to reduce gear transmission noise

3. Cost Optimization
Since baby cradles are a price-sensitive market, using high-end motors may not be necessary. Our approach includes:
- Spur gearbox + brushed DC motor: which is a more cost-effective solution

4. Motor Lifetime
The motor in a baby cradle frequently alternates between forward and reverse rotations. With one forward and one reverse motion counted as one cycle, our motor is designed to:
- Last for over 500,000 operating cycles
