Automatic Baby Cradle Kit

Automatic Baby Cradle Kit is a smart cradle motor system that can automatically rock the crib to help the baby fall asleep peacefully.

It usually consists of a Gear motor, a controller 和一个 bracket, supports timing adjustment and different swing amplitudes. Currently, this product is very popular in the Indian 和 Vietnamese markets.

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
