In high-humidity environments, water droplets may adhere to the friction surfaces of electromagnetic brakes and clutches, resulting in reduced friction before complete drying. Moreover, moisture is a major cause of corrosion in electromagnetic brakes; please pay close attention to this.

I. Humidity and Water Droplets

If the friction surfaces of electromagnetic brakes and clutches are in a relatively high humidity environment, water droplets will adhere to them. Before they are completely dry, the friction will be low. Moreover, moisture is the main cause of rust in electromagnetic brakes. Please pay full attention to this.

II. Foreign Matter

No foreign matter should be mixed into the friction surface. The mixing of grease will cause the friction pads to slip, rapidly reducing the generated friction and causing a sharp decrease in braking effect. The mixing of dust and metal particles will cause wear and damage to the friction pads or rotating parts. The mixing of chemical agents will cause rust and corrosion. Therefore, the brake needs protection during operation. If necessary, use a protective cover to prevent oil stains, dust, and corrosion, and enhance the service life of the brake.

III. High Speed

The high allowable speed of electromagnetic brakes and clutches. Please refer to the parameter table of electromagnetic brakes and clutches from Tuoko Company, or call for consultation. High speed is determined by the high speed of the friction surface. If used beyond this speed, it will lead to the inability to generate rated torque, abnormal wear, or overheating and deformation.

IV. Temperature

Electromagnetic brakes and clutches are Class B insulated, with a normal temperature rise of 40°C. The operating temperature at thermal equilibrium is not allowed to exceed 100°C; otherwise, the coil and friction parts are easily damaged.

V. Ventilation

Since electromagnetic brakes and clutches generate frictional heat that dissipates to the outside, they should be installed in a ventilated place. When used in places with poor ventilation and heat dissipation, please pay attention to item 2 and use forced ventilation cooling if necessary.

In the field of industrial automation and mechanical equipment, brakes are core components that ensure safe operation and precise control. Their performance directly affects production efficiency and personnel safety. AC brakes, as braking devices driven by AC power, play an irreplaceable role in various industrial scenarios due to their high efficiency, reliability, and rapid response.

Precise control of electrically operated brakes in modern mechanical transmissions

The operating principle of an electrically powered brake is based on electromagnetic attraction. When power is applied to the electrically powered brake, the coil within the electromagnet generates a magnetic field. This magnetic field attracts the iron core, causing it to clamp the brake disc against the friction disc. This clamping action prevents the friction disc from rotating, thus achieving braking. When the power is cut off, the magnetic field in the electromagnet coil disappears, and the clamping action between the iron core and the brake disc also disappears, allowing the friction disc to rotate freely.
