• Air Gap
  

  The air space between the stationery and moving pole face in a solenoid assembly.

• Ampere Turns
  

  The absolute value of magnetic flux in a solenoid assembly determined by the number of turns of copper wire and the magnitude of the current

• Anchor Plate
  

  A thin formed sheet of metal fitted over the mounting studs of a rotary solenoid to provide containment for a scroll type return spring

• Armature Assembly
  The armature assembly of a rotary solenoid comprises of the shaft, hub and armature plate. This is the complete moving element of a rotary solenoid
• Armature Plate
  The armature plate is the large diameter plate forming the main rotating element of a rotary solenoid, it contains the 3 coined ball races used in the Ledex principle to convert linear motion to rotary movement. The coined tracks are hardened for wearability
• Case
  The outer case of a solenoid assembly which provides the main flux path. In the case of a rotary solenoid the case also contains the 3 hardened ball races which convert linear motion to rotary movement using the Ledex principle
• Coil
  Copper windings provide the electrical element for all solenoids, current is passed through the coil to create a magnetic field. Coils can be precision wound, random wound or bobbin wound, performance is optimised when the maximum amount of copper for the space available is achieved
• Duty Cycle
  The duty cycle is defined as the ratio of on time to on + off time in a given cycle, the lower the duty cycle the higher the output that can be obtained from the solenoid, however this can only be achieved in short bursts
• Gross Torque
  The starting torque available from a rotary solenoid before any deductions for return springs etc.
  
• Heat rise
  The rise in coil temperature which results from operating the solenoid, you should expect the temperature rise to be up to 80 deg above ambient when mounted on a suitable heat sink
• Heat Sink
  The maximum allowable watts for each solenoid are specified based on an unrestricted flow of air mounted on a heat sink equivalent to that specified,. An inadequate heat sink or restricted air flow can result in the solenoid coil becoming overheated.
• Holding Torque
  The torque required to free the armature from the energised position whilst under power.
• Hub
  Part of the armature assembly forming the moving pole face of a rotary solenoid
• Lead wires
  Standard temperature rated coils use UL listed PVC insulated lead wires. Class ’H’ coils use PTFE insulated leads.
• Ledex Principle
  Our range of rotary solenoids use the Ledex principle of operation. This employs the inclined plane of 3 ball races to convert linear motion to rotary developed by G H Leland during the 1940’s. It provides almost frictionless conversion of the motion and is widely adapted throughout the industry
• Lubrication
  The ball races of our standard range of rotary solenoids are lubricated with a lithium based grease with temperature capabilities of -54 deg C to in excess of 90 deg C, endurance engineered models are lubricated in a similar manner with a grease suitable for temperatures of -29 deg C to + 121 deg C
• Operation
  Solenoids provide the interface between electrical control and mechanical movement
• Permissible temperature rise
  The permissible temperature rise of a solenoid coil limits the magnitude of the power and therefore the available ampere turns. Heat makes the coil less efficient because it increases resistance reducing ampere turns, flux density and torque or force output
• Residual Magnetism
  

  The magnetism which remains in effect between 2 pieces of magnetic material after the electromagnetic field created by the coil has been removed. An air gap is usually maintained between 2 magnetic poles to minimise the effects of residual magnetism.

• Rotary Solenoids
  Our range of rotary solenoids use the Ledex principle of operation with 3 inclined ball races, as a result they have a small axial stroke which must be allowed for in any application
• Solenoid
  A cylindrical coil of wire acting as a magnet when electric current passes through it, converting electrical energy to mechanical energy.
• Starting Torque
  The torque which is produced by a rotary solenoid in the first 2 degrees of movement from its de-energised position.
• Stator Assembly
  The portion of any solenoid which contains the coil, case and base, the items which remain stationary during operation
• Temperature rise
  The increases in coil temperature above ambient resulting from operating the solenoid. A temperature rise of 80 deg C is typical for a standard solenoid
• Weber
  A unit of magnetic flux
