Custom Design Linear Induction Motors
 H2W has released a number of custom designed Linear Induction Motors, or LIMs, capable of producing high speeds in unique motion profiles. The photo above shows a LIM with a curved profile. The 3-phase coil assembly can be directly connected to the AC line for single speed applications or to an adjustable frequency drive for precise variable control of the speed of the motor. The laminated coil assembly (shown above) is used in conjunction with a customer supplied aluminum and steel reaction plate to produce a force. A customer supplied bearing system is required to maintain the .040” - .060” [1 – 1.5 mm] air gap between the coil assembly and the reaction plate. The length of the reaction plate is equal to the coil length plus the stroke.

Integrated Internal Bearings on Moving Coil Voice Coil Motors from H2W Technologies
 H2W Technologies Voice Coils are ideal for short stroke (typically less than 2 inches) closed loop servo applications. Their compact size allows them to fit into small spaces. They have very low electrical and mechanical time constants. The low moving mass allows for high accelerations of light payloads. These actuators are wound in such a way that no commutation is required for motion to occur. The result is a much simpler and more reliable system. Generally moving coil voice coils have required an external bearing system; however H2W has integrated an internal bearing system that does not add to the outside diameter of the actuator. This is also an inexpensive alternative to the voice coil stage. An additional option for this actuator is the integration of springs, which allow the actuator to operate open loop in oscillatory applications. ...More >> Voice Coil Positioning Stage from H2W Technologies for Short Stroke Positioning Applications
 The Voice Coil Positioning Stage is a compact, small footprint positioning stage. It is ideal for closed loop positioning applications with a short stroke where intricate position, velocity, and acceleration control is necessary.Their compact size allows them to fit into small spaces. They have very low electrical and mechanical time constants. The low moving mass allows for high accelerations of light payloads. The ironless core coil assembly has no magnetic attractive force to the stationary magnet assembly, which reduces the load on the bearing system, which increases the life of the bearing. There are no magnetic drag forces (hysteresis), which allows for higher accelerations. These actuators are wound in such a way that no commutation is required for motion to occur. Electrical devices such as Hall Effects are not necessary. The result is a much simpler and more reliable system. ...More >> Low Cost Dual Rail Positioning Stages by H2W Tech are Very Stable

 This stage was built for a customer who was attempting to move at 20Hz over a short stroke (0.1"). H2W was replacing a similar voice coil stage which had a ball slide bearing assembly. After several million cycles, the friction of the steel balls wore an indentation in the bearing assembly, thus preventing smooth continuous motion of the slide. The stage was modified using New Way Air Bearings. The Air Bearings allow for smooth, frictionless motion without the worry of wear, and allowing for many millions of cycles. The frictionless air bearing makes long life possible.
