Fan heater motor
A fan heater (1) has a motor (M) with motor windings (W) and a rotor that is connected to a fan (V) for delivering ambient air at least partially along the motor windings (W). At least one motor winding is configured as a heater winding (HW) for generating a specific heat output or amount of heat as intended.
PUMP
The pump has an electromagnet for reciprocating a piston, and a first casing member at least partially accommodating the piston and the electromagnet. The electromagnet has a stator core and coils wound around the stator core. The pump further includes a thermal protector disposed on the stator core. The thermal protector is held between the casing member and the stator core. When the thermal protector detects that the stator core has heated up above a predetermined temperature, the supply of electric power to the electromagnet is interrupted to stop the drive of the piston.
