In many industries clutches are used to ensure smooth transmission of mechanical power. Conventional mechanical clutches create many problems in progressive automation of Industries. Electromagnetic clutches are designed to suit any automatic machines. Electrical operation of clutch makes possible push button control of a machine from one or several points & from near or remote plates. Electromagnetic Brakes stop the motor or machine Instantaneously or within desired time.

Application & Scope

These clutches are used for smooth starting of machines. They are more used in machine tools as they are very compact in size. Besides machine toots they also have an application in various types of machines such as; Textile machinery, printing machines, plastic Machines, Multi speed gear boxes & various other machines.

Advantages

• Eliminates wear & tear of starters & contact points.
• Motor need not take heavy current while starting as it starts, with no load condition.
• Low starting torque & less HP motors can be used.
• One motor can drive different mechanisms simultaneously or individually, through number of clutches.
• Clutches & Brakes work on 24 v.D.C. with low wattage. We also supply Transformer
• Rectifier unit where D.C.Voltage is not available.
• We also supply Spring loaded Carbon brush holder to supply power to the slipring of the clutch.

Construction

• Magnet body with plated coil.
• Internal & external plates of hardened steel.
• Armature plate is of low carbon steel & its outer dia is formed with threads & threaded ring is provided of the same for adjustment, of air Gaps.
• The cup is made of steel & its fingers are case hardened.

Electromagnetic clutches and brakes are widely used in all the Industries. M/s. MAGNA CORE is making almost all electromagnetic multi disc clutches & brakes required for the industrial purposes. Magnacore made type clutches are those which are used specially for following Purpose.

• Air gap multiplate clutches with sliprings : Series 0-006-00
• Stationery field multiple clutches from Magnacore made type clutches.

These clutches are more popular in Series 0-010-00

Air Gap Multiple Clutches with Sliprings 0-006-00

These models can be applicable in wet operation with alternative friction linings. The design is such that through the actuating pressure produced by the magnetic coil is indirectly transmitted to the plates by number of pins sliding through the coil. To achieve maximum torque and accurate operation, it is recommended to maintain air gap between the magnetic body and the armature plate. In these type of clutches air gap can be maintained periodically because the armature is fitted at the back side of magnetic body.

Stationery Field Multiple Disc Clutches 0-010

These stationery field multiple disc clutches are widely used in all industries. Due to the elimination of brushes wear is automatically compensated. These clutches are secured against rotation by the locking lug. Six key ways are provided for locking of the stationery coil body. These clutches used in wet operation condition internal lubrication is to be arranged while the engagement of the clutch. General lubrication is to be considered necessary to ball bearings. Due to that lowest running temperature is normally possible in working of the clutch.

Slipring type toothed clutches can transmit higher torque compare to other multi disc clutches of same size. Toothed electro magnetic clutches provide positive connection between two shafts by remote electric control. Toothed clutches can only be engaged either a rest or at a small speed difference between the two parts. Toothed clutches can only be operated when the two shafts or pieces of machinery to be coupled are stationery running at the same speed or at very slightly different speeds, but it may be disengaged at any speed under load. When compared with other types, toothed clutches transmit more torque with less physisal dimensions. Toothed clutches can be operated in wet or dry condition and don't require any adjustment during life time.

Construction

It consists of a magnet body and toothed ring and slipring mounted on the outside and armature plate. Springs on guide pins ensure t hat, the toothed rings are kept apart when the clutch is disengaged. Normally there are two parts, one is keyed to driving shft and the other one is keyed to driven shaft. The adopter plate can be supplied for mounting the armature plate. When the coil is energized it produces magnetic flux and the clutch is engaged and transmits the torque. All clutches operate from 24V DC supply. Generally slipring type toothed clutches can be operated in wet or dry condition although wet operation is preferable.

Scope

These clutches are used for heavy torque transmission in rolling mils, cement factory, steel industries, machine tools industries for synchronizing conveyor, generator, wire winders, heavy duty machines, hoist, cranes traverse and trolley drives, winches etc.

Designs

There are three designs available in toothed clutches

• Toothed clutch with slipring
• Toothed clutches without slipring with ball beraing or withour ball bearing.
• Toothed clutches where springs engaged electrically released.

~

EK type clutches & brakes are used to control starting and stopping of machines. There are many designs in electromagnetic clutches & brakes, such as, single disc, multiple disc, stationary field, with slipring, dry wet etc.

Application

These are multiple disc oil immersed (magnetic flux passing through discs) type clutches with slipring. They are used specially in machine tools like milling, lathe, grinder, bearing machine etc.

Features

Dimensionally clutches and brakes are same. When slipring is not provided it is used as a brake. Plug type brush holder is required to supply current to clutches only. And brakes are provided with flying leads. No wear adjustment is required during working. After complete wear set of friction discs needs replacement. Standard voltage is '24 volts D.C.

Technical Details

There are three types of mountnting in every size.

Basic Design : To mount on two shaft with keyway or splines.
• 'B' Design : Bearing Mounted - To Mount on single shaft with gear or sprocket. .
• 'C' Type Design : Clutch is assembled on bush and cup is found free to couple with driven shaft.

  Construction & Working

In all designs clutches and brakes consist of magnet body with sealed coil and internal and external discs, arma-ture plate and cup. Internal plates and Armature plate are running with one shaft and external plates are running with another shaft. When D.C. supply is feeded to magnet body all plates are locked with each other and power is trasmitted from one shaft to another shaft.~

Magnacore Make Equivalent to-EKR-Z Type Clutches

These sationery field tooth clutches can transmit a higher torque compared to stationery field multi disc clutches. It can be operated in wet or dry condition though wet operation is preferable.

Magnacore Make Equivalent to-EKR-Z Type Clutches

These are stationey field multiple disc clutches which maintenance free & used in gear box of machine tools to transmit power. They are without slipring.

 The telescopic brushes are required the good transfer of current supply to the slip-ring of clutches fitted in different machine tools.

These E.M. multiple disc clutches are available to suit in dry or wet operation. These clutches work with a gap, when the power is disconnected the reset force generated and the driven section is disconnected without delay. These are slipringless clutches & working on 24V DC.

Magnacore Make Equivalent to-EKR-Z Type Clutches

These clutches/brakes are used for smooth starting of machine. They are more used machine tools as they are very compact in size.
