Abstract

A motor, including: a stator, a rotor, and a motor controller. The motor controller is connected to a network interface circuit (NIC). The motor can be directly connected to a network, which makes it possible for technicians to facilitate remote control, debugging, remote diagnosis, and troubleshooting. The motor is easy to be identified, and features improved functions, wider application range, and more convenient use.

Claims

1. A motor, comprising

a stator;

a rotor; and

a motor controller;

wherein

said motor controller is connected to a network interface circuit (NIC).

2. The motor of claim 1, wherein said motor controller is a digital signal processing unit.

3. The motor of claim 2, wherein

said digital signal processing unit is a micro controller unit (MCU), or a digital signal processor (DSP);

said MCU or said DSP operates as a main control chip for said motor, as a control chip for said NIC, and as a processing chip for the TCP/IP protocol.

4. The motor of claim 3, wherein said NIC is an Ethernet adaptor.

5. The motor of claim 3, wherein

said NIC comprises a RJ45 interface;

said motor controller is disposed in a control box; and

said RJ45 interface is disposed on said control box.

6. A control method for a motor, said motor comprising a stator, a rotor, and a motor controller, said motor controller being connected to a network interface circuit (NIC), said method comprising

connecting said NIC connected to said motor controller to a network;

and

controlling said motor controller, and communicating with said motor controller whereby transmitting data by a control terminal connected to said network.

7. The control method of claim 6, wherein communication between said control terminal and said motor controller is based on the TCP/IP protocol.

8. The control method of claim 7, wherein

said motor controller is a signal processing unit;

said digital signal processing unit is a micro controller unit (MCU), or a digital signal processor (DSP); and

said MCU or said DSP operates as a main control chip for said motor, as a control chip for said NIC, and as a processing chip for the TCP/IP protocol.

9. The control method of claim 8, wherein said NIC is directly connected to a WAN, or firstly connected to a LAN, and then to said WAN via a gateway of said LAN, or only to a LAN.

10. A cluster control system comprising multiple motors, comprises

multiple motors each comprising a stator, a rotor, and a motor controller;

and

multiple control terminals;

wherein

said motor controller is connected to a network interface circuit (NIC), and to a network via said NIC;

said control terminal is connected to said network;

said control terminal communicates with said motor via said network and the TCP/IP protocol; and

said control terminal reads status information of said motor in real-time, and sets parameters for said motor whereby controlling operation thereof.

11. The cluster control system of claim 10, wherein said control terminal is a computer.
