Abstract
A motor for a blender may include an armature and a coil. The coil and armature operatively receive power from a power source. The blender may include a controller and a memory. The memory may store instructions that, when executed by the controller, cause the controller to dynamically alter an output current to the motor. The instructions adjust the output current supplied to the motor at a given speed to reduce torque of the motor to match a preferred torque versus speed profile.
Claims8
A blender system, comprising:
- a blender base;
- a brushless motor disposed within the blender base;
- and
- a controller and a memory storing instructions that, when executed by the controller to apply a transfer function to a speed of the motor to determine an upper limit of torque associated with the motor, cause the controller to determine an output signal to be applied to the motor based on the speed of the motor and the determined upper limit of torque associated with the speed of the motor.
