摘要:
A power recovery system utilizing a relatively high temperature waste heat fluid to drive an expander (12). The expander (12) is operatively connected to an electrical generator (14). A dynamic brake (22) is connected to the expander (12)to regulate the speed thereof when the expander (12) is operating at other than steady state conditions.
摘要:
Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetically induced force that introduces a force threshold that, in effect, provides a threshold to part movement and confers a degree of hysteresis, preventing movement until a sufficiently large energizing force is applied. The effect may be further altered by use of an additional magnetically induced force interaction with at least one further member to urge or slow movement once started and/or to prevent movement once a new position is reached.
摘要:
The invention relates to a machine tool deceleration device, in particular a hand-held machine tool deceleration device, for a portable machine tool, comprising at least one magnetic deceleration unit (14a; 14b). According to the invention, the magnetic deceleration unit (14a; 14b) comprises at least one movably mounted claw segment element (16a; 16b) to change at least one parameter of a magnetic field of the magnetic deceleration unit (14a; 14b).
摘要:
In order to pivot a first magnetic unit (20) about a metallic workpiece (2) using a supra-conducting spool such that the same is inductively heated, an exterior magnetic field can be generated, driving the first magnetic unit (20) by means of a second magnetic unit (30).
摘要:
A system includes an eddy current brake. The eddy current brake includes a back plate and a first inductor. The first inductor includes a pole coupled to the back plate and a winding disposed about the pole, wherein the winding is configured to conduct an electric current to generate a magnetic field. At least one of the back plate and the pole 104 includes a plurality of laminations.
