Linear actuator covers multiple
positions
The maximum force of the linear actuator and the torque of the rotary actuator have been increased as much as 300%.
Alpha Gearheads' Ternary BLM actuator rounds off the existing all-in-one linear system that merges mechanics with intelligence Ternary is a combination of several separate components that unites precision mechanics, electronics and integrated control and software in a single package

Couplings solve common drivetrain problems
Alpha Gear Drives offers a full line of torque limiting, bellows and economy class servo couplings.
The system includes a servo drive and precision mechanics with a ball screw spindle and a stainless steel connecting rod.
Depending on the model, the maximum force of the linear actuator and the torque of the rotary actuator have been increased as much as 300% and the maximum linear velocity and speed are 11% higher.
Ternary is suited to applications where a pneumatic cylinder isn't enough and a servo is too expensive and too complicated.

Software tool turns PDAs into 'teach' pendants
Alpha gear drives is introducing its new pockeTern software toolkit, a portable version of its powerful proTern software.
Alpha's linear system allows multiple positions to be controlled with utmost precision over an unlimited number of field buses.
Compactness, strength, intelligence and precision are the hallmarks of the linear actuator.
The linear unit can be used to design flexible machines that are easily adapted to product changes or future expansions.
The dynamics of the integrated servo drive enable the achievable clock pulse rates to be more than doubled in practical duty.
The fact that separate switch cabinets and additional wiring or cable ducts can be dispensed with further increases the saving.
And since the Ternary actuator system integrates everything in a single device, fewer components are needed, enhancing operating reliability.
Supported by force control, Ternary not only approaches exactly specified positions - it can also be held or pressed against a body with a predefined force.
Ternary positions and stops quickly with a strong holding force and no vibration.
As with the existing series, Profibus, CANopen or DeviceNet can be supplied in addition to the serial and parallel interfaces.
Over and above the higher drive performance and lower noise level, a serial interface is standard with all fieldbus variants, making the data setting software considerably easier to use.
The Ternary BLM system's internal memory now allows 64 positions to be programmed and controlled instead of the previous 16.
Ternary BLM is equipped with a pulse input and A/B encoder output function to permit the actuator to be directly controlled if necessary without a bus interface.
A variant with an absolute encoder is currently in the pipeline.
Ternary BLM also brings commercial advantages, using only around a third of the power of compressor solutions with pneumatic cylinders.
The linear system requires no maintenance and complies offers IP65 protection.
