Abstract
Exercise machines and linear motor systems for use in exercise machines are provided herein, where the linear motor provides a resistance force in response to a force generated by a user performing an exercise. The linear motor systems include a programmable logic and force generation control system, which is programmable to control the resistance provided by the linear motor.
Claims18
An exercise machine that comprises:
- a linear motor system having a linear motor including:
- a base;
- a header support;
- a pair of linear shafts that extend from the base to the header support and a magnetic shaft being located between the linear shafts and extending from the base to the header support;
- a forcer slidably attached to the linear shafts that moves along the magnetic shaft, wherein the linear motor acts as a force producing element to provide resistance to a force generated by a user when performing an exercise.
An exercise machine that comprises:
- a linear motor system having a linear motor including a forcer that moves along a magnetic shaft, wherein the linear motor acts as a force producing element to provide resistance to a force generated by a user when performing an exercise,
- the linear motor system further including a programmable logic and force generation control system operatively connected to the linear motor system, the programmable logic and force generation control system comprising a microprocessor that is programmable to control the resistance provided by the linear motor.
An exercise machine that comprises:
- a linear motor system having a linear motor including a forcer that moves along the a magnetic shaft, wherein the linear motor acts as a force producing element to provide resistance to a force generated by a user when performing an exercise,
- where the forcer is linearly displaced in response to the force generated by the user when performing an exercise and starts at a home position when the user is in an initial position for performing the exercise, rises vertically to a stroke displacement as the user reaches a full stroke of the exercise, and returns to the home position as the user finishes the exercise by returning to the initial position.
A linear motor system for producing a resistance force in an exercise machine in response to a force generated by a user when performing an exercise, the linear motor system comprising:
- a base;
- a header support;
- a pair of linear shafts that extend from the base to the header support;
- a magnetic shaft located between the linear shafts and extending from the base to the header support;
- and
- a forcer slidably attached to the linear shafts that moves along the magnetic shaft to produce the resistance force.
