Motors
Commercial motors and industrial motors are designed to keep specific systems and equipment running, including residential HVAC systems, farm equipment, pumps, and vacuum systems. Motor supplies are used to repair and maintain motors, improve their efficiency, mount them in place, and adapt them for use in specific tasks. Motor speed controls and soft starts help regulate the speed of electric motors for optimal control and performance.

DC Motors
DC Motors
DC motors produce high starting torque and power to drive equipment such as conveyor belts, elevators, cranes, and hoists. They use permanent magnets or electromagnetic windings to convert direct current electrical energy into mechanical energy. These motors rely on voltage to change speeds and provide positioning. Brushless blower motors do not lose energy through friction and heat, making them more efficient and durable than standard motors. DC motor and control assemblies feature adjustable speed motors for use on constant, or diminishing, torque applications. DC permanent magnet motors can operate at multiple speeds and adapt to different power sources. DC wound field motors draw low amounts of electric current to power equipment for lifting heavy loads. Small engine starter motors turn over the engine in outdoor equipment by engaging a flywheel, driveshaft, or other type of gear. Stepper motors use electrical pulses to provide precise positioning and speed control.
Definite Purpose Motors
Definite Purpose Motors
Definite-purpose motors are AC motors with mechanical features designed for a specific purpose or application. They are driven by alternating current and require low power to start. These motors are commonly used to replace old or broken motors with the same specifications in compatible equipment. Brake motors stop movement in a system or keep loads from moving when the power is turned off. Farm-duty motors and washdown motors are designed to withstand water in damp, dirty environments. Pump motors power pumps to move liquids and gases through a system. Hazardous location motors are used in equipment in areas where explosive materials may exist. Instant reverse motors power equipment that reverses direction frequently. Vacuum motors move clean, dry air through the motor to blow air out or provide powerful suction. Vector motors can power machinery at a wide range of speeds while maintaining torque. Vibrator motors provide vibration for shifting and moving materials on the equipment.

General Purpose AC Motors
General Purpose AC Motors
General purpose AC motors are electric motors driven by alternating current. Also called induction motors, they use a rotating magnetic field to generate energy. AC motors are efficient, durable, and quiet, making them a good choice for powering pumps, blowers, conveyors, and machine tools. Single-phase AC motors use single-phase power that is typically found in homes. Three-phase AC motors work on three-phase electrical power, which is commonly found in large-scale industrial applications. Three-phase IEC metric motors have metric dimensions and are commonly used in countries outside the U.S. to power equipment that requires International Electrotechnical Commission (IEC) electrical standards.
HVAC Motors
HVAC Motors
HVAC motors power HVAC equipment to provide heating, cooling, and air circulation in indoor environments. They are commonly used in air coolers, roof ventilators, air circulators, and condensing units. Belt-drive motors drive a belt or pulley to power equipment and allow for adjustable operating speeds. Direct-drive motors include condenser fan motors, pedestal fan motors, room air conditioner motors, and unit heater motors. They mount directly to the drive shaft of HVAC equipment, which minimizes friction during operation and increases efficiency. Direct-drive motors produce less noise and vibration than belt-drive motors. C-frame motors are suitable for use in small fans, such as in range hoods and electric heaters. Draft booster motors and oil burner motors power fans and pumps in gas furnaces and oil burners. OEM replacement motors, 3.3″ diameter motors, and 4.4″ diameter motors are typically used to replace damaged motors with the same specifications in compatible equipment.

Motor Supplies
Motor Supplies
Motor supplies and accessories help keep motors running, prevent or repair damage to motors, and adapt motors for use in specific tasks. Motor capacitors provide voltage to bring motors up to speed quickly at startup and can also improve their efficiency while running. Commutator maintenance products clean or polish the commutator in brush-style motors or generators to help extend their operating life. Motor mounting supplies help secure motors in place. Motor rotating switches respond to the centrifugal force of the motor shaft to open and close. Rainshields stop liquids or small solids from getting inside motors and causing potential damage. Power transmission accessories allow motors to transmit power to equipment.
Pump Motors
Pump Motors
Pump motors are commonly used in irrigation, pool and spa, pressure washer, and water pumping systems to move liquids. Car wash motors are totally enclosed for protection in wet and humid environments where frequent washdowns occur. Carbonator pump motors are suitable for use in liquid transfer pumps, vending machine pumps, and other hub-mounted pumps. Close-coupled pump motors take up less space than frame-mounted pump motors and are often used in centrifugal pump applications. Fire pump motors are used to power pumps in fire sprinkler systems. Jet pump motors and submersible deep-well pump motors pump water from a well or draw water up from groundwater sources. Oil well pump motors provide high-slip and high-starting torque required by heavy oil-drilling operations. Pool and spa pump motors circulate and filter water to help keep swimming pools clean. Pressure washer motors resist corrosion and can be used in applications where the pump is moving hot or cold water at high pressures.

Motor Replacement Parts
Motor replacement parts are used to repair broken or damaged motors, helping keep them in good condition and extend their life.
Speed Controls, Encoders and Soft Starts
Speed Controls, Encoders and Soft Starts
Speed controls, encoders, and soft starts are parts and accessories that help improve motor performance. Drive reactors and output filters extend the life of motors by reducing heat and audible noise, dampening overshoot peak voltage, and limiting the magnitude of voltage spikes. Motor speed controls are adjustable speed controls for AC, DC, and universal motor applications that require constant or diminishing torque, such as fans, blowers, pumps, conveyors, and mixers. Rotary encoders, or shaft encoders, track the turning of motor shafts to generate digital position and motion information. Soft starts reduce the mechanical stress put on a motor at startup for a smoother start. Vector motor accessories, such as brakes and encoders, provide precise control of speed and positioning of vector motors.
