Title:
LINEAR MOTOR AND ROTOR MOVEMENT POSITIONING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/007199
Kind Code:
A1
Abstract:
Disclosed in the present application are a linear motor and a rotor movement positioning control device. The linear motor comprises a stator and a plurality of rotors, wherein the rotors are provided with permanent magnet arrays. The stator comprises a linear stator module and an arc-shaped stator module connected in sequence. The linear stator module and the arc-shaped stator module are all provided with coils and encoder arrays. Each rotor is provided with a first sensing element and a second sensing element, wherein when the first sensing element and the second sensing element are configured in such a manner that, when the rotor moves on the linear stator module, a first signal sent by the first sensing element is read by the encoder array on the linear stator module, and when the rotor moves on the arc-shaped stator module, a second signal sent by the second sensing element is read by the encoder array on the arc-shaped stator module. The movement of the rotors of the present invention can be switched on guide rails in different shapes.
