|Motor parts and motor
AC Motor StartersAC motor starters are used to turn-on and turn-off electric
motors and motor-controlled equipment. They use solid-state or electromechanical
technologies, and are designed for single-phase or three-phase motors.
CommutatorsCommutators are rotary electrical switches that are used to
reverse the direction of a current between a rotor and an external circuit.
DC Motor StartersDC motor starters combine a controller (most often a
contactor) with overload protection, allowing a motor or motor-controlled
equipment to be turned on and off.
Gearboxes and GearheadsGearboxes and gearheads, also called gear reducers
or speed reducers, are power transmission devices that use a gear arrangement in
an enclosed housing to transfer energy, increase torque and reduce speed from
one device to another. Gearboxes may also be referred to as gear reducers or
Motor BasesMotor Bases are mounts for electric motors. Most bases
have an adjustable bolt pattern for various motor sizes as well as
adjustments to position the motor. Most mounts are designed to fit various
NEMA motor sizes.
Motor CoilsMotor coils are used with motors, generators, stators,
Motor ContactorsMotor contactors are relays with large current
capacity for connecting and disconnecting a motor from the power
supply. Typically, motor contractors are multi-pole for control of all
current carrying conductors.
Motor Starters and ContactorsMotor starters and contactors
are motor-starting devices. They combine a contactor with overload
protection and are designed for starting AC or DC motors.
Power Take-offs (PTO)Power take-offs (PTOs) are extensions
of a vehicle's drive train that can be engaged to power auxiliary
equipment such as plows, augers, winches, and many other material
handling, construction, and agricultural implements.
