Device for controlling the speed of a washing machine motor.

摘要

The invention relates to a circuit for adjusting the high and low spin speeds of a machine. The motor speed is adjusted by phase angle control circuit which receives an adjustable d.c. signal from the output 37 of the circuit shown in Figure 2. During normal washing, only switch 29 is closed providing a first d.c. level at output 37. During slow speed spinning switch 24 is closed to provide a second d.c. level at output 37 variable by resistor 40. At high speed the switch 43 is additionally closed to provide a third d.c. level variable by resistor 42. The resistors 40 and 42 are preferably ganged to simplify operation.
