Physical exercise apparatus for isokinetic and eccentric training |
摘要 |
A physical exercise apparatus for isokinetic and eccentric training which employs a permanent magnet electric motor/generator as the means for generating positive and negative loads. An electrical braking circuit which employs zener diodes governs the speed of a permanent magnet electric generator by providing a sharp increase of resisting torque with increasing rotation speed when the rotation speed reaches a predetermined value.
