These new products – which were recently introduced to the market – offer solutions that drive motor “system” performance. JVL has introduced what it says is the first wireless integrated servo motor and a modular concept that makes it extremely easy to adapt the motors for a wide range of applications. Other new products are pursuing the same goal by providing daisy chaining for up to 16 axes and offering motor/drive integration that uses closed-loop control to eliminate missteps and loss of synchronism.
Wireless Integrated Servo Motors
The MAC00-FB4 module from JVL International facilitates control of MAC wireless integrated servo motors, providing total freedom from cables. The new module uses a direct Bluetooth connection to the motor for set up and control which offers the same possibilities as a serial connection. Functionality is identical to the company’s nano PLC module but, instead of using the serial connector, the module is equipped with an antenna. The module can be programmed via JVL’s MacTalk software. Control is typically done from a mobile phone or a PC. MacTalk can be used directly on a PC and commands or programs can be sent from your own program.
A two-phase stepper motor with a micro-stepping driver and DSP-based motion controller, the SMC-Pollux motor/controller/driver package, has been introduced in the North American market by MICOS USA. The motion controller utilizes a multi-drop serial interface that allows daisy chaining of up to 16 axes. Ultra-high micro-stepping rates up to 5000 micro-steps per full-step provide motion that is extremely smooth and keeps mechanical resonances to a minimum. VT-80 and DT-80 stages are available as standard products with the integrated SMC-Pollux units. MICOS specializes in high precision positioning components and systems for vacuum, ultra-high vacuum, clean room and extreme climate environments down to 77 Kelvin.
Stepping Motor and Driver System
AlphaStep from Oriental Motor is an innovative stepping motor and driver unit that uses closed-loop control to eliminate missteps and loss of synchronism. The system uses a newly developed sensor to detect step motor rotor position by sensing the change in inductance between the moving rotor and the stationary stator teeth. This position detection sensor constantly monitors the rotor movement and, if synchronism is about to be lost, closed loop control is used to ensure there is not a loss of control or position. The ac input AS series has the pulse input and built-in controller packages. The dc input ASC series has a pulse input package.Three motor types include the standard motor type, IP65 rated and a geared motor type.
