A new range of miniature servo drives, no bigger than a pack of cards, has been launched in the UK by Motor Technology. Manufactured by Italian firm Axor Industries, the new Mack Nano drives have been designed as an ultra-compact, low-cost alternative to AC, DC and stepper applications that would benefit from the higher performance of a servo system without the usual hike in cost.
Targetting low voltage applications, the Mack Nano drives are suitable for use on machinery for printing, textiles, labelling, sorting, sewing and packaging. They are also useful for instrumentation, lab equipment, battery powered systems, autonomous vehicles (including AGVs), conveyors, actuators and systems including door operators and antenna positioners.
The new drive modules pack in functions such as control for brushless and DC servo motors, stepper motors and sensorless motors. They include control modes such as analogue and digital speed and torque demand, clock and direction signals, and various serial communication and fieldbus options.
These drives are supplied in two housings, depending on the power rating and functions selected. There are four voltage levels 48, 60, 110 and 140V DC, with current ratings up to 10Amps, 50Amps, 35Amps and 25Amps respectively. Peak current of twice the nominal rating is available for up to three seconds.
The Mack Nano also has a number of homing routines, gearing functions and analogue positioning capability for simple applications where a controller is either not desirable or viable.
