Torque measurement device

摘要

Provided is a torque measurement device including a stator in which a space portion is formed by a first annular ring and a second annular ring having protrusion pieces, a ring-shaped magnet disposed in the space portion, and a collector assembly including a first collector member and a second collector member to form at least one insertion space in which a magnetic element is disposed, wherein the insertion space is formed by bending an end of the first collector member and an end of the second collector member toward the space portion.

主权项

1. A torque measurement device comprising:
a stator including a space portion formed by a first annular ring and a second annular ring having protrusion pieces; a ring-shaped magnet disposed in the space portion; and a collector assembly including a first collector member and a second collector member to form at least one insertion space in which a magnetic element is configured to be disposed, wherein the insertion space is defined by an end of the first collector member and an end of the second collector member extended toward the space portion, and wherein the first collector member and the second collector member comprise: flux transfer surfaces disposed near the first or second annular ring; opposite surfaces connected to the flux transfer surfaces and bent in facing directions; and insertion surfaces connected to the opposite surfaces and bent toward the space portion between the first annular second annular ring and second annular ring configured to dispose the magnetic element therein.
