Electromagnetic deenergization brake (non-excited electromagnetic brake) is a friction plate brake pressed by a spring when the electromagnetic disengagement (release) is de-energized. It can be matched with electric motor into a new type of brake motor, and can also be used in mechanical transmission system to realize fast parking and accurate positioning. It can be used in occasions such as safe (anti-dangerous) braking when power is off.
Electromagnetic power-off brake (non-excited electromagnetic brake) has the advantages of simple structure, wide adaptability, low noise, and reliable braking. It is widely used in various mechanical transmission devices. It is an ideal in industrial modernization. Executive component.
Electromagnetic power-off brake (non-excitation type electromagnetic brake) can be used safely under the condition that the relative humidity of the surrounding air is not more than 85%. Class B insulation is adopted around the brake, and the voltage fluctuation does not exceed 5% and-15% of the rated voltage. Its working mode is continuous working system.
Note: After installation, the hollow bolt must be unscrewed and locked on the rear end cover or flange of the motor.
Electromagnetic power-off brake (power-off brake) has the advantages of compact structure, convenient installation, wide adaptability, low noise, high working frequency, sensitive action, and reliable braking. It is an ideal automatic actuator.
The main material of electromagnetic power-off brake: iron core and armature are mostly made of No. 10 steel. For large brakes, No. 8 steel is mostly used. The winding generally uses F-grade heat-resistant grade. The friction disc generally requires a friction coefficient of more than 0.5. There are also springs.
The brake is externally connected with a half-wave rectifier to rectify single-phase alternating current into direct current. After the winding is energized, a magnetic field is generated, which attracts the armature back, and the armature compresses the spring fixed in the core.The electromagnetic power-off brake of the motor is completed by the brake, which is divided into two categories: power-on brake and power-off brake. The power-on brake is used for braking occasions requiring precise positioning, and the power-off brake is used for occasions where the equipment must be reliably stopped after power failure: that is, if the equipment cannot be stopped in time after power failure, it will cause casualties, equipment damage, product scrapping and other serious accidents that endanger safe production.
The working mechanism of the electromagnetic power-off brake is that the brake does not restrict the rotating shaft when the motor is energized, and when the motor is powered off or the motor is powered off for any reason, the braking function of the electromagnetic power-off brake is activated, the motor rotating shaft is locked, and the motor rotor is converted from dynamic to static in a short time, and the equipment is transferred to a reliable parking state.
An electric motor is a device that converts electrical energy into mechanical energy. The starting process of the motor will undergo a state transition from static to dynamic; after the motor is powered off during operation, it will undergo a transition from dynamic to static due to inertia. Most equipment has no requirement for the length of time from moving to static, but some equipment such as elevators, cranes, automated production lines, etc. must be stopped within a very short period of time after power failure, which introduces our topic today, motor brake control.
