Electrical DC Motors are continuous actuators that convert electrical energy into mechanical energy. The DC motor achieves this by producing a continuous angular rotation that can be used to rotate pumps, fans, compressors, wheels, etc. As well as conventional rotary DC motors, linear motors are also available which are capable of producing a continuous liner movement. There are basically three types of conventional electrical motor available: AC type Motors, DC type Motors and Stepper Motors. The DC Motor or Direct Current Motor to give it its full title, is the most commonly used actuator for producing continuous movement and whose speed of rotation can easily be controlled, making them ideal for use in applications were speed control, servo type control, and/or positioning is required. A DC motor consists of two parts, a “Stator” which is the stationary part and a “Rotor” which is the rotating part. The result is that there are basically three types of DC Motor available.
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. Electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.
Delfire series of motors are designed to be a part of smoke and heat control ventilation systems. These systems create a smoke free layer above the floor by removing the smoke. Thus, they improve conditions for safe escape/rescue of people, animals and the protection of property. They also permit the fighting of fire while still in its early stage. They are also used with jet fans to convey smoke, NOx, carbon monoxide and other gases from tunnels, car parks, basement areas and the likes. In many cases they operate in the hazard prevention mode. In case of fire outbreak, the temperature rises rapidly. Delfire motor work for a guaranteed period of 1 or 2 hours at a continuous temperature of 300, 250 & 200º Celsius, depending upon requirement. These can be single or two speed motors and are governed by the harmonized European standard EN12101.
Bluvolt motors conform to the dimensional requirement laid down in the standard IEC 72-1. IEC 72-1 specifies the dimensional requirements for all the frame & flange sizes. All motors are multiple voltage multi-frequency 50 Hz, F class insulation (H on request), S1 continuous duty service, IP55 protection (IP56, 66) IE2 or IE3 efficiency classs tropicalized winding suitable for inverter power supply
Bluvolt offers Delphi ATDC (DC Brakes), AT24 ( 24 V DC Brakes) and ATAC (AC Brakes). These are of electromagnetic type and normally OFF i.e. the braking action occurs in the absence of power supply. The brake insulation class is F. The brake lining is asbestos free as per most recent EEC Directives pertaining to Workplace Hygiene and Safety. All brake assemblies are protected against corrosion by painting or heat galvanizing and resined winding. The parts most subjected to war are specially treated to ensure they become wear resistance.
