Description

Brushless motor for walking machine

Technical Field

The utility model relates to a brushless motor especially relates to a brushless motor for walking machine.

Background

The walking machine is a sports apparatus for simulating walking, and after being electrified, the motor drives the conveyer belt of the walking machine to rotate, so as to form relative motion with people on the walking machine, thereby simulating walking. The motor that present walking machine was used mainly goes on through there being the brush motor, but has the brush motor to need rely on the brush to commutate, relies on the brush switching-over, and the friction is big, and the loss is big and generate heat greatly, and the life-span is short to when the application has the brush motor on sports equipment, need use the flywheel, the diameter of flywheel is too big, leads to the treadmill to accomplish the flattening design hardly. Therefore, it is highly desirable to design a brushless motor device suitable for use in a walking machine.

Disclosure of Invention

The purpose of the invention is as follows: the to-be-solved technical problem of the utility model is to provide a brushless motor for walking machine solves and uses the loss that has the brush motor to meet on the walking machine big, short-lived, bulky scheduling problem, does not use the brush, reduces interference and wearing and tearing, has reduced the maintenance cost, has adopted the external rotor to replace the flywheel, has effectively reduced the volume.

The technical scheme is as follows: a brushless motor for walking machine, including rotor and the stator of setting in the rotor inside, the rotor includes pipe fitting, upper cover, lower cover and magnetic shoe, and the magnetic shoe is fixed to be set up at the internal surface of pipe fitting, and upper cover and lower cover are fixed respectively on the both sides terminal surface of pipe fitting, the stator includes motor shaft, blade of silicon steel, bearing, hall PCB subassembly, and the blade of silicon steel is fixed on the motor shaft, twines the enameled wire on the blade of silicon steel, and hall PCB subassembly sets up on the enameled wire, the motor shaft both ends are connected through the bearing respectively and are covered at upper cover and lower cover, and the rotor can rotate on the motor shaft.

Furthermore, the upper cover is provided with a vent hole.

Furthermore, the lower cover is provided with a vent hole.

Further, the upper cover and the lower cover are fixed on the end faces of the two sides of the pipe fitting through bolts.

Furthermore, the upper cover is provided with a groove which can be engaged with the conveyor belt of the walking machine.

Furthermore, the lower cover is provided with a groove which can be engaged with the conveyor belt of the walking machine.

Has the advantages that: the brushless motor can replace a brush motor used on a walking machine, reduces loss, prolongs service life, and carries out effective design according to the structure and working characteristics of the walking machine, thereby greatly reducing the occupied space of the motor and improving the working stability of the motor and a transmission belt.

Detailed Description

The brushless motor for a walking machine according to the present embodiment has a structure as shown in fig. 1 and 2, and includes a rotor 1 and a stator 2 disposed inside the rotor 1, where the rotor 1 includes a pipe 11, an upper cover 12, a lower cover 13, and magnetic shoes 14, the magnetic shoes 14 are fixedly disposed on an inner surface of the pipe 11, and the upper cover 12 and the lower cover 13 are respectively fixed on end surfaces of two sides of the pipe 11 and can be connected by bolts. Preferably, the upper cover 12 and the lower cover 13 may be provided with ventilation holes to effectively dissipate heat during operation. The stator 2 comprises a motor shaft 15, a silicon steel sheet 16, a bearing 17 and a Hall PCB assembly 18, wherein the silicon steel sheet 16 is fixed on the motor shaft 15, the silicon steel sheet 16 is made of silicon steel, contains a small amount of silicon elements and has higher resistivity and magnetic permeability, an enameled wire is wound on a part, connected with a sheet structure on the outer surface, inside the silicon steel sheet 16, of the extending part, the Hall PCB assembly 18 is arranged on the enameled wire, and the Hall PCB assembly 18 is a semiconductor, can detect the change of a magnetic field in the motor and determines to supply power to one phase of three-phase power. Both ends of the motor shaft 15 are connected to the upper cover 12 and the lower cover 13 through bearings 17, respectively, and the rotor 1 can rotate on the motor shaft 15. The conveyor belt of the walking machine is sleeved on the rotor 1, the stator 2 is fixed on the walking frame, once the stator 2 is electrified, the stator 2 generates a magnetic field, and the magnetic shoe 14 drives the rotor 1 to rotate under the action of magnetic force. In order to further prevent the belt from slipping and increase the stability of use, the upper cover 12 and the lower cover 13 are provided with grooves which can engage with the belt of the walking machine.

The working process of the motor is that the magnetic shoe 14 of the rotor 1 generates a constant magnetic field, when the power is switched on, the current flows through the enameled wire wound on the silicon steel sheet 16 through the Hall PCB assembly 18, the Hall PCB assembly 18 detects the position of the rotor 1 of the motor in real time, and then the motor is communicated with corresponding currents according to the position of the rotor 1, so that the stator 2 generates a rotating magnetic field with uniformly changed direction, and the rotor 1 rotates in relative motion under the action of magnetic force to drive the conveyor belt because the motor shaft 15 is fixed on the frame of the walking machine and cannot rotate.
