“The servo drive design is simple. The heart of the unit is an integrated servo pump consisting of a servo motor and an internal gear pump. Its flow rate is perfectly matched to the cylinder surfaces of a differential cylinder,” says Grant Robinson, Voith Turbo VP – EMEA Division, Mining and Metals Southern Africa.

The unit also includes intelligent control via fieldbus connection, a pressure limiter, and a small compensating tank. This control system design renders other components, such as expensive valve engineering, unnecessary.

“As a result, energy losses caused by throttle effects do not occur with the

CLDP. This increases the machine energy savings by up to 50 percent, compared to machinery using conventional drive systems,” adds Robinson.

The self-contained linear drive combines electromechanical and hydraulic systems, making it compact, dynamic and energy-efficient. Additional   benefits include; overload protection, a high power density and virtually wear-free operation.

Robinson indicates that the servo drive is essentially a hydraulic gearbox with an almost unlimited gear ratio, making it ideally-suited for use in applications with high dynamic speed requirements and high power demands.

“Thanks to the integrated servo pump, the energy efficiency is far greater than that of conventional solutions. This also makes it ideal for all direct   linear motions – primarily when dynamic response, reproducibility and      reliability are needed,” Robinson continues.

The CLDP servo drive can be easily integrated into new or existing        machines. Only the electrical connection for the servo motor is needed.
