Orient Electric Limited is an Indian multinational electrical equipment manufacturer, based in New Delhi and part of CK Birla Group. It makes fans, lighting, home appliances and switchgears. Orient Electric has manufacturing facilities in Kolkata, Faridabad, Hyderabad and Noida. It exports fans from India to over 30 international markets. [4] [5]
A brushless DC electric motor (BLDC), also known as an electronically commutated motor, is a synchronous motor using a direct current (DC) electric power supply. It uses an electronic controller to switch DC currents to the motor windings producing magnetic fields that effectively rotate in space and which the permanent magnet rotor follows.
The key components of a ceiling fan are the following: An electric motor; Blades (also known as paddles or wings) usually made from solid wood, plywood, steel, aluminium, MDF or plastic; Blade irons (also known as blade brackets, blade arms, blade holders, or flanges), which hold the blades and connect them to the motor.
Electric fan in Thailand Two box fans. Between 1882 and 1886 Schuyler Wheeler invented a fan powered by electricity. [9] It was commercially marketed by the American firm Crocker & Curtis electric motor company. In 1885 a desktop direct drive electric fan was commercially available by Stout, Meadowcraft & Co. in New York. [10]
In vector control, an AC induction or synchronous motor is controlled under all operating conditions like a separately excited DC motor. [21] That is, the AC motor behaves like a DC motor in which the field flux linkage and armature flux linkage created by the respective field and armature (or torque component) currents are orthogonally aligned such that, when torque is controlled, the field ...
A Totally Enclosed, Fan-Cooled (TEFC) electric motor is a type of industrial electric motor with an enclosure that does not permit outside air to freely circulate through the interior of the motor. [1] An external fan blows outside air over the frame of the motor to cool it. This motor is arguably the most commonly used motor in ordinary ...
An internal fan-cooled electric motor (colloquially, fan-cooled motor) is a self cooling electric motor.Fan cooled motors feature an axial fan attached to the rotor of the motor (usually on the opposite end as the output shaft) that spins with the motor, providing increased airflow to the motor's internal and external parts which aids in cooling.
A traditional radial flux BLDC motor places a rotor made of permanent magnets inside the stator. The stator contains support known as a yoke, which is outfitted with "teeth", individually wrapped with electromagnetic coils. The teeth function as alternating magnetic poles.
