With over 8,000 employees worldwide, HYDAC is one of the leading suppliers of fluid technology, hydraulic and electronic equipment.
The KineSys team is your partner for expertise in drive solutions for Kinematic Systems.
The name KineSys is derived from the composition of the words kinematics and system.
KineSys variable speed drives (DVA) are characterized by the perfect symbiosis of hydraulics and electronics. The integrated control system allows the drive motor to be controlled on demand. This results in a great potential for energy savings, as only the amount of energy required is made available. Energy savings of up to 70%, depending on the machine cycle, can be achieved. Due to the condition-optimized adaptation of the KineSys solution, the power loss is reduced to a minimum and the complexity on hydraulic side is drastically reduced.
Electric cylinders, also called electric lift cylinders or electromechanical cylinders, are electrically driven adjustment actuators. Unlike fluidic cylinders, these are already fully functional systems.
The KineSys product name HEZ stands for Hydac Electric Cylinder. Within the HEZ, the rotary motion of the electric motor is converted into a linear motion by a screw drive. Different positioning forces, travel speeds and duty cycles can be realized by the choice of gearbox and drive.
Based on a variable speed drive, full integration of frequency converter and cooling system, the CO3 power pack represents a very cost effective compact hydraulic supply unit. Main application area of this plug&play solution are machine tools, especially lathes.
Variable-speed drives are considered to be particularly energy-efficient and quiet because both the required volume flow and the hydraulic and thus the electrical power are provided to the consumer as needed. Hydraulic volume flow and speed of the motor are reduced, noise level of fan and hydraulic pump is minimized. The drive train can even be switched off completely if there is no demand. Accordingly, a variable speed drive is significantly quieter and more energy efficient compared to conventional drives with constant motor speed.
HYDAC KineSys uses external gear pumps (PGE) and internal gear pumps (PGI) as well as other pump types on request.
Electric cylinders (HEZ) are "closed axes". An environmentally harmful "leakage" can be excluded. Unlike hydraulics, no oil is drawn from a tank and pumped through various components into the hydraulic cylinders. In a HEZ, there is no liquid "medium" to transmit the power. This function is performed by the motor, the gearbox and the spindle. The rotational movement of the motor is converted into a linear movement. Only grease lubrication protects the components and internal friction is reduced. Environmental damage can be prevented by using electric cylinders.
Yes, via current or torque values of the motor. Depending on the requirements, external force sensors can also be used for higher accuracy.
Yes, via rotary (or angle) encoders directly on the motor shaft or via external linear position encoders.
Yes, both mechanically coupled and software synchronized operation are possible.
Yes, the prerequisites are the performance and cycle data in order to provide the appropriate dimensioning.
Yes, for simple applications such as extending and retracting at a constant speed, a frequency inverter is not necessary.
The HYDAC HFI-MM (Hydac Frequency Inverter – Motor Mounted) drive controller is a device for speed control of three-phase asynchronous motors.
The drive controller can be used motor-mounted (with "Standard" adapter plate) or close to the motor (with "Wall-mounted" adapter plate).
HYDAC HFI-CM (Hydac Frequency Inverter – Cabinet Mounted) drive controller for permanently excited synchronous motors.
A servo drive system with a wide power range, flexible fieldbus connection, integrated safety technology and IEC61131 programmability.
No, the 400V power supply for the frequency inverter does not have to be shielded. Only the cable between the motor and the inverter must be shielded.
