In another embodiment, the Hall sensor 61 may be made of GaAs, and the output VH of the Hall sensor 61 may have a slope of about -0.06% / ° C.

The first position sensor 170 may further include a temperature sensing element 63 capable of sensing an ambient temperature. The temperature sensing element 63 can output the temperature sensing signal Ts to the driver 62 according to the result of measuring the temperature around the first position sensor 170. [

For example, the hall sensor 61 of the first position sensor 190 may generate an output according to the result of sensing the magnitude of the magnetic force of the first magnets 130-1 to 130-4.

The driver 62 can output the driving signal dV for driving the hall sensor 61 and the driving signal Id1 for driving the first coil 120. [

For example, the driver 62 receives the clock signal SCL, the data signal SDA, and the power supply signals VCC and GND from the control unit 830 using data communication using a protocol, for example, I2C communication can do.

The driver 62 outputs a drive signal dV for driving the hall sensor 61 and a drive signal dV for driving the first coil 120 using the clock signal SCL and the power supply signals VCC and GND, (Id1) can be generated.
