DC motor brake, mechanical brake, regenerative braking, dynamic braking, reverse braking The mechanical brake is the brake,
electric brake.
Reverse Braking: the positive power supply is cut off immediately plus reverse power,
The motor to quickly stop, when the motor speed down to zero, installed in Reverse relay of the motor shaft immediately send a signal
to cut off the reverse power Prevent really reversal of the motor
Many different types of DC machines, the best flexibility to choose the type of motor and braking requirements braking method.
In general, the higher the rotational speed of DC motor, the greater moment of inertia, so the braking requirements are more urgent
and necessary. Fortunately, the DC motor controls are extremely easy to reverse, so the braking method and flexible.
Following Introduction to common types of braking method:
1short-circuit braking. Also known as the self-damping brake. In order to avoid short-circuit current is too large and the general use of
high-power small-value resistor shorted, also known as the braking resistor damping.
2 anti-repression action. The brake very quickly, usually used in the demanding professional to control the motor. The principle is: the
reverse voltage to the motor when the brake.
3 mechanical brake. Mechanical contact of the friction brake. This method is easy, and is generally used in less demanding place.
4 magnetic damping brake. Generally used in the workplace requires brake gently and slow braking time.
