A blocking assignment is one in which the statements are executed sequentially, i.e., first statement is executed and variable is assigned  a value then second is executed and so on. A non blocking assignment is  one in which statements occurs conturrently, only non blocking assignments should be used in sequential circuit.

e.g.

initial

begin

a=b; //blocking

c<=a; //nonblocking

d=c; // blocking

end

In this example firstly the value of b is assigned to a and this value is assigned to c only after execution of first statement. the second and the third statements are executed simultaneously, i.e. value a ais assigned to c and previous value if c is assigned to d.

An electric motor is an electrical machine that converts electrical energy into mechanical energy.

Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.
