10VRX

VR resolvers (variable reluctance resolvers) are angular displacement sensors that detect motor rotation angles and provide analog output signals. Featuring a simple structure without rotor windings or brushes, they offer excellent durability in harsh environments subject to heat, vibration, and dust. This robustness directly contributes to extended equipment service life and stable operation.
MinebeaMitsumi’s VR resolvers achieve highly accurate angle detection through advanced manufacturing techniques, maintaining copper wire winding precision to within half the specified tolerance.
To further enhance durability, TIG (tungsten inert gas) welding is used for wire connections instead of conventional soldering. During this process, the molten metal forms a spherical bead that encapsulates the copper wire, creating a highly resilient joint that minimizes the risk of vibration-induced wire breakage. This uniform bead shape also streamlines visual inspection; any joint defects, such as a deformed or collapsed bead, are easily identified during manufacturing. Ultimately, this ensures the consistent quality and reliability you need for your end products.
