Is there such thing as an electric clutch?
Electronic Clutches are used in a variety of Sorting and Packaging applications, including: Food Processing Equipment. Packaging Machinery. Conveyor Drives.
What is an eddy current clutch?
Eddy current clutch defined: An eddy current clutch (ECC) drive is a device used to convert constant speed rotation input into adjustable speed output. A typical drive consists of two concentrically rotating members (input & output) separated by a small fixed air gap.
What causes an electric clutch to fail?
The retaining tab is mainly to prevent rotation when the clutch is applied, and it is necessary only to pin it in place so it is somewhat free-floating. Bolting it tightly can create hub-and-shaft misalignment and bearing prestress. This can lead to quick clutch failure and even drive damage.
What are the main components of an electromagnetic clutch?
The main components of EM clutch shown in the figure below (Figure 2) are a coil shell, an armature, rotor, and hub. The armature plate is lined with friction coating. The coil is placed behind the rotor. When the clutch activated the electric circuit energizes the coil, it generates a magnetic field.
How does eddy current drive work?
An eddy current drive controls speed by regulating a direct-current (DC) excitation coil on a magnetic rotor, rotating concentrically with a steel drum, driven by the motor at full speed. Like the pumps and electric motors that drive them, eddy current drives are rotating machines.
What is Dynodrive?
“Dyno Drive” consists of a totally enclosed, fan cooled (TEFC), flange type three-phase squirrel cage induction motor is mounted on to an eddy current clutch, having a projected, self-ventilated common frame design. There is no physical contact between motor and clutch.
Why do we use electromagnetic clutches?
Role of Electromagnetic Clutches: To Transmit and Cut Off Power. Electromagnetic clutches are a mechanical element to transmit and cut power on the driven side with an electromagnetic force. Put simply, they can disconnect and connect power without stopping the power.
How does an electromagnetic brake work?
Electromagnetic brakes are also called electro-mechanical brakes or EM brakes. They slow or stop motion using electromagnetic force to apply mechanical resistance, or friction. An electrical current goes through a coil on the brakes to create a magnetic field strong enough to move an armature on or off a magnetic face.
What is eddy current clutch?
An eddy current drive, also known generically as a magnetic drive, eddy current clutch or magnetic clutch, is an electro-mechanical variable speed drive that uses a constant speed motor as the input. The eddy current drive is installed between the motor and the driven equipment.
What is difference between eddy current and induced current?
The main difference between eddy current and induced current is that induced current refers to currents flowing in coils of wire in a closed circuit whereas eddy current refers to loops of currents flowing within pieces of larger conductors due to electromagnetic induction.
How does an eddy current drive work?
The eddy current drive uses a DC magnetic field to link the input and output shaft. The strength of the field is dependent on direct current applied to coils on the drive’s rotor. As the current is increased, so is the strength of the magnetic field.
