Notes:
1 Overload and Locked Rotor:
When the motor is running, it generates heat due to the energy conversion that occurs inside the coil and the iron core, and the temperature gradually rises. The load is within the rated range, and the heat generation and heat dissipation are balanced, and the coil of the motor will not be burnt. However, it will cause heat under overload and lockedrotor conditions. When the running time is too long, the insulating film on the enameled wire of the coil is dissolved, causing a short circuit between the enameled wires and burning the motor.
2 When Running at Low Speed:
For DC motors, carbon brushes are generally used. The rotating commutator rubs against the carbon brushes, creating sparks at the notches of the commutator. When the motor is running at a low speed, the carbon brush powder that is easily generated by the friction between the commutator and the carbon brush will accumulate in the commutator slot, causing a short circuit and burning the motor and driver. Please be very careful.
3 Precautions on the PWM Controller:
When using the PWM controller, the carbon brushes have a shorter service life than in the rated voltage (or fixed voltage) state. In addition, depending on the frequency of use, carbon brushes may wear out quickly. The frequency of PWM control of DC motors is generally 1020KHz, and repeated ONOFF during PWM control can save energy. However, the parts used in the motor are similar to the frequency of use, which will cause resonance and heat. Please pay full attention to use.
In the PWM control state, when using the builtin motor of the electrolytic capacitor, the motor may not rotate at a certain fixed frequency. Please try to use varistor to hide the motor. (Need to do related tests)
4 Regarding Inertia and Braking:
After the motor is powered off, the rotor will still rotate due to inertia, which is the inertia of the DC motor. If you want to stop the rotation immediately, you can shortcircuit the positive and negative terminals after turning off the power. The use of this kind of brake is to use the motor to generate electricity (reverse current). The current may increase temporarily and shorten the life.
5 Treatment of Floor Motor:
Because the magnetic tile is a brittle material, the DC motor may break the magnetic tile once it falls, causing the motor to block and cause burns. Please do not use the motor after it has landed at a high altitude. .
