Title:
STAGE LAMP WITH HIGH-PRECISION ROTARY POSITIONING
Document Type and Number:
WIPO Patent Application WO/2022/142323
Kind Code:
A1
Abstract:
A stage lamp with high-precision rotary positioning. The stage lamp comprises a pivoting member and a support member, wherein the pivoting member is pivoted to the support member and comprises at least one light source (110) used for generating a lighting effect, the pivoting member is driven by a pancake motor to rotate, the pancake motor comprises a stator (400) to be energized to generate a magnetic field, and a rotor (500) sleeving on the stator and driven by the magnetic field, the pivoting member is fixedly connected to the rotor (500), the support member is fixedly connected to the stator (400), or the pivoting member is fixedly connected to the stator (400), and the support member is fixedly connected to the rotor (500). As the rotor (500) sleeves on the stator (400), the end face area is larger than that of a rotating shaft of a traditional rotating shaft motor, and the rotor cannot shake randomly. A transmission assembly is omitted, such that transmission errors are prevented, and positioning is more accurate. In addition, the stator (400) or the rotor (500) is directly connected to the pivoting member and can be used as a pivoting shaft, and no extra space is needed for mounting an electric motor. In addition, compared with a traditional rotating shaft motor, the height of the electric motor can be reduced since the rotating shaft is omitted.
