Mechanical brakes mainly use friction to consume the kinetic energy of the system and produce a braking effect.
For the same energy consumption, the greater the speed of the shaft is higher, the smaller the corresponding torque that must be transmitted. Because power = torque × angular velocity.
The arrangement of the mechanical brake on the high-speed shaft can reduce the resisting torque that the brake must provide with the same braking power, thereby reducing the size of the brake and reducing its cost.
What does the torque of the motor and gearbox mean?
Consistently, the nacelle is the basic part of wind energy production. Generally, when the wind turbine is operating normally, the turbine faces the direction of the incoming wind. The nacelle and the turbine are in the same direction. direction, they are therefore also oriented towards the direction of the nacelle. Generally, the wind turbine In addition to the aplike electric, it consists of four main parts, namely the turbine, the generator and the engine room. There are also wind turbines with gearboxes, and their generators and nacelles are integrated. When the wind turbine is operating normally, it faces the direction of the incoming wind.
1. The torque of the motor and gearbox refers to the torque generated at a certain speed after deceleration by the gearbox to the rated power of the motor.
2. Torque: It is a special torque that makes an object rotate. It reflects the load capacity of the motor and gearbox.
3. Torque of motor and gearbox (N·m) = rated motor power (W)/(2*π*speed/60).
4. It can be seen from Article 3 that when the motor power is constant, a low speed can obtain a higher torque.
