In addition to their durability, motors transform electrical energy into mechanical energy. They are commonly found in industrial electric powered equipment and appliances. The agency hereby declares the personal property listed below to be surplus pursuant to Environmental Conservation Law.
AC motors are used for a wide variety of applications because of their flexibility, efficiency and noiseless operation. They work by converting electrical energy into mechanical energy via magnetic fields in the copper wound stator and rotating rotor. Depending on the application, AC motors can operate with various voltage levels and frequencies. Voltage is important because it determines the amount of current that can be drawn by the rotor and how quickly it can reach its rated speed. In addition, the rotor is energized by a conductor (windings) in the stator that creates a field that generates torque in the rotor. A variable-frequency drive can be added to a motor for precise control. Surplusrecord has a variety of electric motors in stock. We also carry a range of frame sizes including 56C. Our electric motors are available as-is, E-ok (electrically functional but will need some reconditioning), reconditioned and rebuilt.
The vast majority of industrial electric motors run on direct current (DC). We stock a broad selection of used and refurbished surplus DC motors from top manufacturers. These motors can be found in mixers, cranes, power tools and generators. They also power household appliances like vacuum cleaners. There are three main types of brushed DC motor: series, shunt and compound. Each type differs in how the field windings are connected to the armature circuit. Series-wound DC motors have the rotor armature and field windings connected in series. This allows for much higher speeds but does not allow for very precise speed control. This makes these motors ideal for applications that require high starting torque but do not need constant speed, such as air conditioning units.
Many modern devices – from cordless mixers to portable music speakers, toothbrushes and electric razors to automatic door operators – rely on gear motors for their power transmission. They’re also used in a wide variety of industrial equipment. Gear motors consist of an electric motor and gears, which create the kinematic chain that converts input speed and torque into output shaft rotational velocity. They come in both right-angle and inline designs, with worm, bevel, hypoid and spur gearing systems most commonly utilized. Integrated motor and gear unit design eliminates the need for separate motor and gearbox shaft couplings. This improves efficiency and reduces the risk of misalignment, which can cause bearing failure due to fretting corrosion.
Gear motors can be powered by AC or DC electric motors and are available with a variety of reduction ratios to suit various applications. This includes everything from food and beverage equipment to robotics. Most manufacturers provide performance curves to help end users select the best model for their application.
