Abstract:
A height adjustable desk includes a worksurface, a first leg and a second leg connected to the worksurface. The first leg is provided with a first motor to drive a first lifting apparatus for telescoping the first leg, while the second leg is provided with a second motor to drive a second lifting apparatus for telescoping the second leg. Each of the first motor and the second motor is provided with a magnetic device and two sensors. The magnetic device has several N-pole sections and S-pole sections, and the sensor detect a change of a magnetic field when the motor is turning. A control unit receives the signals of the sensor, and changes a speed of at least one of the motors until the signals are synchronous again when the control unit found that the signals are not synchronous.

Claim (Index 6):
A method of keeping two motors synchronously turning, comprising the steps of:\n A. providing a first magnetic device on a shaft of a first motor and a second magnetic device on a shaft of a second motor, wherein each of the first and the second magnetic device have a plurality of N-pole sections and a plurality of S-pole sections alternately arranged in an annular pattern; B. providing a first front sensor and a first rear sensor to sense a change of a magnetic field of the first magnetic device when the first motor is turning, and providing a second front sensor and a second rear sensor to sensing a change of a magnetic field of the second magnetic device when the second motor is turning, wherein there is a phase difference between signals of the first front sensor and the first rear sensor, and there is a phase difference between signals of the second front sensor and the second rear sensor; C. combining the signals of the first front sensor and the first rear sensor to obtain first combinative signals, and combining the signals of the second front sensor and the second rear sensor to obtain second combinative signals; and D. comparing the first combinative signals with the second combinative signals, and when the first combinative signals and the second combinative signals are not synchronous, changing a speed of at least one of the first motor and of the second motor until the first combinative signals and the second combinative signals are synchronous again.
