Abstract

The invention discloses a transverse flux permanent-magnet planar motor, and relates to the filed of motors. The transverse flux permanent-magnet planar motor solves the problems of limited stroke of a rotor, low thrust density, complicated structure of the motor, low current control accuracy and the like in the conventional permanent-magnet planar motor. The primary of the motor consists of a plurality of motor units; each w motor units consist of m2 phase armature units; and the m2 phase armature units form a phase armature unit array; the intervals between rows and the intervals between columns are the same; each phase armature unit consists of a phase unit iron core and a phase unit winding; each phase unit iron core with perforations consists of two iron core units, the perforations are formed by overlapping tooth spaces of the two iron core units, two teeth of each iron core unit are arranged along the horizontal direction of a cross section, and a magnet yoke section is connected between the two teeth; a coil is wound into a phase of phase unit winding through the perforations; and the tooth pitch tau a between two adjacent phase unit iron cores along the X direction or Y direction is equal to [1+j / m]] tau p. In addition, the motor has the advantages of simple structure and easy realization of modulization, and the stroke of the motor is not limited.

Description

technical field [0001] The invention relates to the field of motors, in particular to a permanent magnet planar motor. Background technique [0002] Modern precision and ultra-precision processing equipment has an urgent need for high-response, high-speed, high-precision planar drive devices, such as machining, electronic product production, mechanical loading and unloading, manufacturing automated instrumentation equipment, and even robot drives. Usually these devices are powered by a rotary motor, and then converted into linear motion by mechanical devices such as belts and ball screws. Due to the complexity of the mechanical device, the transmission accuracy and speed are limited, and frequent adjustments are required, resulting in high cost, poor reliability, and large volume. The original planar driving device was realized by two directly driven linear motors, and a stacked driving structure was adopted. This structure increased the complexity of the transmission syste...
