Definitions

  • the present invention relates to a motor control apparatus for providing an exercise resistance and an automatic rewinding function, and more particularly to a motor operating with a microprocessor for selectively executing two different output modes: an electric generator mode or a power machine mode of the motor and the motor is applied in various different fitness equipments such as a weight lifting machine and a rowing exercise machine for stretching exercises and thus simplifying the components of the fitness machine.
  • a traditional weight lifting machine (not shown in the figure) usually uses metal weights as the source of exercise resistance, and the weight lifting machine comes with complicated components and large volume that result in wasting spaces and generating noises. Therefore, manufacturers try to replace the metal weights or flywheels with a motor operated in an electric machine output mode and provide an exercise resistance to various different fitness equipments such as the fitness machines with a design of an electric motor as disclosed in U.S. Pat. Nos. 6,790,163 , 5,762,584 and 5,435,798 , so as to provide the expected exercise resistance.
  • the aforementioned patent uses a force measuring device to measure the data of a force exerted onto a rope, and the detected data is compared with a predetermined value of the microprocessor to control the clockwise and counterclockwise rotation of the motor, or even provide an appropriate safety response based on the existence of an abnormal force exerted onto the rope.
  • the force measuring device usually has to go through a "stable" process each time when a user sets the unit measuring time (which is similar to a fluctuation of the readings at an early stage of a measurement occurred when we stand on a scale to measure our body weight), and thus we can obtain the best measured reading, but such arrangement greatly slows down the response of the overall circuit system.
  • the conventional resistance control apparatus is unable to cope with the natural response speed of a general exerciser's brain and limbs, unless the exerciser is operating and exercising at a very slow constant speed.
  • the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally invented and developed a motor control apparatus for operating a motor at different output modes, so as to achieve the expected effect of simplifying the structure of the motor and reducing the components as well as maintaining a long life expectancy of the motor.
  • a motor control apparatus of the kind mentioned that is characterized in that a microprocessor is operated together with a current detection feedback loop and a motor rotation speed detection loop for precisely controlling a quick random operation of a motor, such that the motor axle can control a loss braking unit and a power driving unit based on the existence of an external force, and the motor can be switched automatically to an electric generator output mode or an electric machine output mode.
  • the so-called “electric generator output mode” of a motor refers to an output mode that converts mechanical energy (external force) into electric energy
  • the so-called “electric machine output mode” of the motor refers to another output mode that converts electric energy into mechanical energy.
  • a motor can selectively carry out two different output modes through different circuit layouts, and it relates to the basic principle of electromagnetic induction, and the present invention is a novel control apparatus with a design based on such natural law and applied in various different fitness equipments for stretching exercises such as a weight lifting machine and a rowing machine.
  • a microprocessor 10 is operated together with a current detection feedback loop 12 and a motor rotation speed detection loop 14 for precisely controlling the quick random operation of a motor 20, such that an axle 22 of the motor 20 can quickly control a loss braking unit 40 and a power driving unit 30 based on the existence of an external force, and the motor can automatically switch to an electric generator output mode (for providing an exercise resistance) or an electric machine output mode (for providing the automatic rewinding function).
  • the microprocessor 10 commands a power driving unit 30 to stop the operation through an announcement of the current detection feedback loop 12, and a loss braking unit 40 is electrically conducted, and then a load resistance 50 consumes and eliminates the energy produced in the electric generating mode.
  • the microprocessor 10 commands the power driving unit 30 to be electrically conducted, and supplies electric energy from a power supply end 60 to start winding in the winding direction B, and the loss braking unit 40 stops the operation synchronously through the same current detection feedback loop 12.
  • the current detection feedback loop 12 monitors the current values of both power driving unit 30 and loss braking unit 40 all the time, so that the operating procedure of the actual application requires a user to set a desired exercise weight or resistance (hereinafter referred to as "Current Output Setting") from a parameter setting end 70.
  • Current Output Setting a desired exercise weight or resistance
  • the current detection feedback loop 12 will detect the occurrence of the generated current and will immediately return a message to the microprocessor 10, so that the motor 20 will quickly switch to the electric generator output mode. If the external force is paused or released, the generated current will disappear, and thus the motor 20 will switch to the electric machine output mode. This repeated operation can actually simulate the expected effect similar to the natural gravitational force of the metal weights or the winding motions.
  • the generated electric energy of the motor 20 or the torque of the rewinding are set from the parameter setting end 70 in advance, so that the microprocessor 10 can make an appropriate control (for controlling the magnitude of current) according to the predetermined settings, but the basic operating and control method of a motor is a prior art and will not be described here.
  • the load resistance 50 eliminates the generated electric energy mainly by converting the electric energy into heat energy which is consumed or dissipated.
  • the invention also can build a conducting path (not shown in the figure) to conduct and eliminate the electric energy appropriately, so as to prevent the occurrence of the "plugging" phenomenon.
  • the motor rotation speed detection loop 14 is provided for monitoring the rotation speed of the axle 22 of the motor 20 all the time, and computing the inertia of the axle 22 and the gravitational acceleration, and thus the motor rotation speed detection loop 14 can detect the user's exercise conditions during the whole course of exercise, and the microprocessor 10 can adjust and control the current output settings of the loss braking unit 40 and the power driving unit 30 quickly to match the user's expected weight setting for the whole course of exercise. In other words, the whole course of exercise can be monitored and controlled to simulate the natural exercise conditions, such that a user can achieve the isokinetic muscular training effect.
  • an appropriate safety response (such as stopping the operation of the overall circuit or retarding the rotation speed of the motor 20) will be performed according to the built-in program of the microprocessor 10.
  • the microprocessor 10 operates according to the settings of the built-in software program, which is a prior art and thus will not be described here.
  • the motor 20 After the current output setting is completed, the motor 20 immediately supplies the corresponding current output in the electric machine output mode.
  • a natural gravitational force similar to the metal weights is applied to a transmission belt 24.
  • the design of the present invention is close to the actual exercise conditions.
  • the built-in timer (not shown in the figure) of microprocessor 10 sets the current output time of the motor 20. In other words, if the transmission belt 24 is not pulled within the set time, the power will be disconnected timely to protect the motor 20.
