Title:
【発明の名称】磁気的心取りおよび停止を有する制限角度トルクモ-タ
Document Type and Number:
Japanese Patent JPH0614772
Kind Code:
B2
Abstract:
A 2-pole limited angle torque motor (1) including a rotor assembly (2) having one or more permanent magnets (5) which are magnetized in the diametrical direction and a stator assembly (3) having a pair of stator magentic pole blades (22, 23) surrounded by a high density layer wound stator coil (20), with stator pole flanges (28, 29) at opposite ends of the stator magnetic pole blades which create a cross flux through the stator and rotor assemblies that produces a limited angle turning torque in the motor. The permanent rotor magnets (5) along with stator magnetic poles (22) and magnetic housing (17) produce a magnetic reluctance torque that can be controlled to obtain a desired magnetic centering or de-centering spring rate for the rotor (2) at a particular torque or power level. A magnetically saturating flux path may also be made to occur in the motor at the end of the rotational design stroke of the motor to provide a magnetic stop for the rotor shaft (15).
