Press machine with modular linear actuator system

A linear-actuated press machine comprises a press ram with a tool, a first linear actuator having a first actuator rod, a second line actuator having a second linear actuator rod, a high-speed motor coupled to the first linear actuator for providing a high-speed condition on the press ram, a first high-torque motor coupled to the first linear actuator, and a second high-torque motor coupled to the second linear actuator. The press machine (i) advances the tool toward the part by operation of the high-speed motor associated with the first linear actuator, (ii) forms the part with the tool by simultaneous operation of the first high-torque motor associated with the first linear actuator and the second high-torque motor associated with the second linear actuator, and (iii) retracts the tool from the part by operation of the high-speed motor associated with the first linear actuator.

Problem

How can vibration in electric motors and rotors be reduced?

Solution

linear-actuated press machine comprises a press ram with a tool, a first linear actuator having a first actuator rod, a second line actuator having a second linear actuator rod, a high-speed motor coupled to the first linear actuator for providing a high-speed condition on the press ram, a first high-torque motor coupled to the first linear actuator, and a second high-torque motor coupled to the second linear actuator.

Key novelty

The press machine (i) advances the tool toward the part by operation of the high-speed motor associated with the first linear actuator, (ii) forms the part with the tool by simultaneous operation of the first high-torque motor associated with the first linear actuator and the second high-torque motor associated with the second linear actuator, and (iii) retracts the tool from the part by operation of the high-speed motor associated with the first linear actuator.
