Abstract
A slicer for cutting slices of elongated food products includes a machine housing and a slicing blade that is held by the machine housing. An electric slicing motor drives the slicing blade, and a control unit actuates the slicing motor using a pulse-width modulation. The control unit includes a microcontroller and a motor output stage. The microcontroller is configured to generate pulse-width-modulated control signals by varying at least one of an amplitude, a frequency or a pulse width of the control signals and to forward the control signals to the slicing motor.
Claims19
A slicer for cutting slices of an elongated food product, the slicer comprising:
- a machine housing;
- a circular slicing blade held by the machine housing;
- a carriage configured to move back and forth with respect to the machine housing and to carry the elongated food product;
- a stop plate configured to set a slicing thickness of the elongated food product disposed on the carriage;
- an asynchronous electric slicing motor that rotates the circular slicing blade;
- a control unit that actuates the asynchronous electric slicing motor using a pulse-width modulation, the control unit including a microcontroller and a first motor output stage connected to the asynchronous electric slicing motor,
- wherein the microcontroller is configured to generate pulse-width-modulated control signals by varying at least one of an amplitude, a frequency, or a pulse width of the control signals as a function of a load status of the asynchronous electric slicing motor, and
- wherein the first motor output stage is configured to forward the control signals to the asynchronous electric slicing motor to rotate the circular slicing blade.
