Linear Electro-Magnetic Actuators

What is an LHDC Linear Actuator? Motor producing force in one direction Friction-free non-contacting action Hysteresis-free bi-directional force Force is proportional to current Single phase coils, commutation not needed Base on "voice coil" principal

Moving Coil or Moving Magnet?

• Most LHDC actuators work either way
• Move coil for low moving mass
• Move magnet for better heat transfer

Why Use LHDC Linear Actuators?

• Precision positioning to &lt0.1 nanometer
• Force efficient: force/mass ratio to 100 NT/kg
• Power efficient: motor constants to 20 NT/rootW
• Fast time constants, no metal in coil

Size, Travel and Clearance are User-Definable

• Optomize for your application
• Travel from 0.1 to 400 mm
• Clearance from 0.1 to 25 mm
• Force up to 200 newtons
• 4 week delivery in most cases

Three Types to Select From

CS Actuator has high efficiency and low cost

EC Actuator is compact with large travel

LD Actuator has 4 to 8 actuators in a single unit
