How Mixer Grinder Works
A mixer grinder is a versatile device that we use in our kitchens for grinding and mixing different food ingredients. We use it for making juice, shakes, milkshakes or, grinding harder food items such as meat, nut and veggies. Mixer grinder offers numerous options even though it is easy to use. It makes your kitchen life a little bit easier.
Working Principle of Mixer Grinder:
There is a universal motor inside the mixer grinder which converts electrical energy into mechanical energy. When current enters into the motor, the coil inside the motor experiences a magnetic force that produces torque and it starts rotating the coil according to Fleming's left-hand rule. The blade of the grinder is attached to the motor so the blade also starts rotating with the motor. A universal motor has many parts like an armature, shaft, commutator, brush and plain bearing etc. You can see below parts of motor in more details.
Universal Motor
Universal motor works on both AC and DC current that’s why we called it “Universal”. It has an stator on which field poles are mounted. Field loops are twisted on the field shafts.The stator field circuit and armature is laminated for minimizing eddy currents which induce while operating on AC. The turning armature is of wound sort having straight openings and commutator with brushes laying on it. The commutation on AC is poorer than that for DC because of the current induced in the armature coils. Therefore brushes utilized are having high opposition.
