The H2W Technologies Moving Magnet Non-Comm DC Voice Coil Linear Actuator, model NCM01-04-001-2IB, features a stroke length of 0.10 inches (2.5 mm) and is designed for applications requiring precise motion control. It has a low moving mass of 0.04 oz (1.0 grams) and a total mass of 0.20 oz (5.6 grams), allowing for high acceleration of light payloads. The actuator operates with a resistance of 2.8 ohms and an inductance of 0.10 mH, resulting in a low electrical time constant of 0.04 msec. This actuator can generate a force of 0.10 lbs (0.45 N) at 100% duty cycle and up to 0.30 lbs (1.34 N) at 10% duty cycle. It has a power rating of 2 watts at 100% duty and 16 watts at 10% duty, with corresponding current ratings of 0.8 amps and 2.4 amps, respectively. The actuator's design eliminates the need for commutation, simplifying the system and enhancing reliability. It is suitable for applications that require intricate position, velocity, and acceleration control when paired with appropriate feedback and control systems.
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.
Coupling the actuators with a bearing system (if not supplied), position feedback device, linear servo amplifier and motion controller yields a system that is capable of intricate position, velocity, and acceleration control. These actuators can also be used for precise force control because of the linear force versus current characteristics.
