Direct drive servos are energy efficient

Direct drive servos are energy efficient

A new range of direct drive servo motors has been launched by Motor Technology to provide a solution for machine builders looking for increases in energy efficiency and a reduction in drive components. Direct drive motors are fitted directly to the load, dispensing with the need for additional components such as gearboxes, couplings, belts, chains and sprockets. Servomotors are highly efficient, typically 90 to 95 per cent, and direct drive servos can result in energy savings of up to 50 per cent in some cases. Also, driving the load directly removes the inefficiencies in a power train with more components.


Driving the load direct has the additional advantages of eliminating backlash from gearboxes, couplings and rack-and-pinions. It also eliminates the problems associated with expansion in belt drives or the play in chain, all of which translate into efficiency losses and a requirement for increased maintenance. Direct drives also reduce design-in time, installation time and cut maintenance and down time. The new SKA direct drive linear motors are synchronous, linear, permanent magnet motors designed with iron-core technology.
