6 FAQs about [Servo transformer energy storage]
How much power does a servo press need?
A transformer with a minimum rated power of 2000 kVA is required. For a complete energy management, the drive system of the press example is expanded to include three kinematic energy storage devices with a maximum power of 1000 kW. As a consequence, it is possible to keep the alternat-ing component of the power in the servo press drive sys-tem.
What are the requirements for a servo press supply transformer?
The supply transformer must also be correspondingly larger; and in this particular case, it must have a minimum 1000 kVA rating. When compared to a servo press without any type of energy management, partial buffering of the kinetic energy reduces the load peaks that impact the line supply.
Does a servo press need energy management?
For a servo press without energy management, the mechanical power to be output by the motor – as well as the power loss of the electric system – must always be completely covered by the infeed and the line supply.
How efficient is a servo motor?
Servo motors have a high efficiency of over 90 percent. A high percentage of the electrical energy supplied is converted into mechanical power. The remaining 10 percent or so of the electrical output is lost in the form of heat. To prevent the motor from overheating, this heat must be dissipated.
What is a servo motor?
The result is a smaller and therefore generally more lightweight motor. This conserves valuable raw materials, such as copper for the coils, magnetic material for the rotors, and iron for the motor housing. Servo motors have a high efficiency of over 90 percent. A high percentage of the electrical energy supplied is converted into mechanical power.
How much power does a 2750 kW servo need?
For a mechanical efficiency of 92 %, for 2750 kW forming power, servos with a minimum drive power of 3000 kW are required. For conventional methods, these types of motion tasks are solved using cams and higher order polynomial func-tions, and little or no emphasis is placed on the energy related aspects.
