Motor control device, motor control system using the same and control module of the same
First Claim
1. A motor control device used to be coupled to a pull switch device and to a variable frequency direct current (DC) motor of a ceiling fan, the pull switch device generating a pull switch input signal in response to an operation performed thereon, said motor control device comprising:
- a receiver module used to receive a first remote control signal, and generating a remote control input signal in response to receipt of the first remote control signal; and
a control module used to receive an input voltage, used to be coupled to the pull switch device for receiving the pull switch input signal therefrom, coupled further to said receiver module for receiving the remote control input signal therefrom, and used to be coupled further to the variable frequency DC motor;
based on the input voltage, the pull switch input signal and the remote control input signal, said control module operating the variable frequency DC motor by turning the variable frequency DC motor on or off, or by adjusting a rotary speed of the variable frequency DC motor when the variable frequency DC motor is turned on.

Abstract
A motor control device includes: a receiver module used to receive a remote control signal, and generating a remote control input signal in response to receipt of the remote control signal; and a control module used to receive an input voltage, used to be coupled to a pull switch device for receiving a pull switch input signal therefrom, coupled further to the receiver module for receiving the remote control input signal therefrom, and used to be coupled further to a variable frequency DC motor of a ceiling fan. Based on the input voltage, the pull switch input signal and the remote control input signal, the control module operates the motor by turning on/off the motor, or by adjusting a rotary speed of the motor when the same is turned on.
