Santa Clarita, CA — Linear Motion Actuators — H2W Technologies offers miniature versions of both our moving coil and moving magnet voice coil actuators. Additionally, we offer custom designed solutions to meet your application specifications.

H2W has built its smallest moving magnet voice coil actuator (NCM01-04-001-2IB)to date, with an outside diameter of 0.40 in [10 mm] and a length of 0.735 in [18.8 mm]. It has a stroke of 0.10 in [2.5 mm] and generates a continuous force of 0.10 lbs [0.45 N] and a peak force of 0.30 lbs [1.35 N]. It weighs just 0.20 ounces [5.7 grams]. This actuator utilizes a hardened shaft and sliding contact bushing to ensure long life, and is ideal for oscillatory motion. The compact design allows the actuator to be used in a number of handheld applications. Moving magnet voice coil actuators have built-in bearings so there is no need for the customer to add mass or complexity to their motion system to integrate a bearing, and there are no moving leads to worry about cable management.

Our smallest moving coil voice coil actuator (NCC01-04-001-1X) has an outside diameter of 0.44 in [11.1 mm] and a length of 0.36 in [9 mm]. It has a stroke of 0.13 in [3.2 mm] and generates a continuous force of 0.06 lbs [0.27 N] and a peak force of 0.18 lbs [0.8 N]. It weighs just 0.20 ounces [5.7 grams]. The bobbin has been constructed of plastic to prevent any damping forces that a metallic bobbin would create. The compact design allows the actuator to be used in a number of handheld applications.

Motion Control – Closed-Loop Integrated Stepper Motors in size NEMA34

JVL-Motion-Control-NEMA-34-Stepper-CutawayJVL-Motion-Control-NEMA-34-Stepper-Chart

Birkerød, Denmark – Motion Control – JVL presents a new innovative closed-loop stepper motor technology for its NEMA34 integrated stepper motor range from 3 to 12 Nm. JVL, the European leader in the development of integrated servo and stepper motor technology, has now again developed a new and unique product in the field of integrated motor control.

New Innovative Technology
JVL closed-loop integrated stepper motors, QuickStep®, provide higher torque, faster acceleration, torque control, stall free operation and quieter movements than traditional step motor systems. QuickStep do this with greater efficiency and less motor heating because motor phase current are regulated up and down according to need. Performance of JVL closed-loop steppers are similar to servo motors, but with higher torque and often without need of gearbox, resulting in a more inexpensive solution. Design safety factors have always been high for stepper motors to ensure stall-free operation – now with QuickStep closed-loop control design can be very close to the limit resulting in even lower costs. QuickStep is a true closed-loop control system that compensates step angle errors during a movement and correct errors within a full step. If load becomes too high speed is lowered and position errors will always stay within two full-steps. Smart digital design and very high update rates (36 MHz) means there is no need of any manual adjustment or setup. It works like a perfect stepper motor benefitting from the servo motor technology.
100% Automatic Setup No need to adjust any parameters. JVL closed-loop stepper motors always work fast and efficient to adapt motor to application. Extremely high update frequency: 36 MHz (where other suppliers have down to only 1 Hz update time). Calculations are made in FPGA and not in slow microprocessors.
Energy Saving Like servo motors QuickStep always runs at lowest possible current. This reduces the need for cooling and results in a more “green” solution.
Stall-Free Operation And No Losing Of Steps By always monitoring the actual rotor position, the control algorithm ensures that the motor does not lose any steps and it cannot stall. If the rotor is blocked mechanically it just continues right away when the obstruction is removed.
Torque Control Mode The torque can be adjusted “on the fly” by the user or by the motor’s embedded PLC program. Applications that were previously impossible for a stepper motor can now be achieved.
Higher Acceleration & Speed Stall-free operation means you do not need to worry about setting the motor to a very high acceleration ramp. The motor simply moves the load with the highest possible acceleration at any given time. The result is a much faster machine with more cycles per day.
Factory Loaded Linearization The motor and encoder are calibrated during factory production in order to reach a very high mechanical precision.
Older Motors Are Supported The Closed-loop control mode is backward compatible with older motors equipped with H2-type encoders. By updating the firmware, the user’s application can benefit from the stall-free operation with very high accelerations and lower power consumption.
Full Torque Available The motor is capable of using the full torque according to the torque-velocity curve and therefore the need to have a safety overhead when dimensioning the machine is much less. Smaller motor = lower costs.
Advantages compared to open loop stepper motors
