The motor is the main power source for toys to maintain continuous power. Designers rarely have the opportunity to design a motor in toy production, and mainly choose it. There are many methods and techniques for selecting toy motors.
Toy motors are standard parts or series parts, which are manufactured by specialized manufacturers. Toy companies only need to choose and purchase them. For toy designers, it is very necessary to reasonably select toy motors to make them work in the best condition and keep them for a long service life.
The selection of motors should be based on power, speed, torque, current, efficiency and external dimensions, etc., combined with the designed toy action.

5 methods for selecting motors
5-1. Curve method Each model of motor has its own characteristic curve. When selecting, if a certain parameter is known, the characteristic curve can be used to obtain other parameters.
By analyzing and comparing the characteristic curves of several different types of motors, a more suitable model can be selected.
Four key points of the performance curve:
1. No-load speed (N0) - refers to the voltage when the motor is not subject to any mechanical resistance or load, and the speed measured on the shaft branch, in rpm (number of revolutions per minute).
2. No-load current (I0) - refers to the current measured when the motor is not loaded.
3. Stall torque (Ts) - refers to the torque measured when the motor stops rotating due to loading. However, it is not recommended to do so, because "demagnetization" or overload may damage the motor.
4. Stall current (Is) - refers to the current measured when the motor stops rotating due to overload.
