The Hypothalamus and Pituitary Glands. The hypothalamus makes up the lower region of the diencephalon and lies just above the brain stem. The pituitary gland (hypophysis) is attached to the bottom of the hypothalamus by a slender stalk called the infundibulum. The pituitary gland consists of two major regions: the anterior pituitary gland (anterior lobe or adenohypophysis) and the posterior pituitary gland (posterior lobe or neurohypophysis).
An electric motor is an electrical machine that converts electrical energy into mechanical energy. The reverse of this would be the conversion of mechanical energy into electrical energy and is done by an electric generator.
Depending upon the source of electrical energy, there are two types of electric motors: A.C. Motors: Motor that converts alternating current energy into mechanical energy is called A.C. motor. D.C. Motors: Motor that converts direct current energy into mechanical energy is called D.C. motor.OWER LOSSES IN A DC MOTOR. The basic function of dc motor is to convert electrical energy into mechanical energy. Whole of the input energy is not converted into useful output energy but a part of the input energy is converted into heat and the same is lost.
