DC shunt motors operate using direct current and have their armature and field winding connected in a parallel configuration. DC shunt motors are similar to other types of DC motors in that they include the same components: They come with a commutator, an armature and field winding.Know More
There are three major types of DC motors: Series motors, compound motors and shunt motors. A DC shunt motor derives its name from the way it is wired €” the armature is connected in parallel (shunt) with the field coil. The interaction between the magnetic field of the field coil and that of the armature is what causes the motor to rotate. This configuration provides an independent path for current flow, which allows for more efficient speed regulation. The speed of a DC shunt motor can be regulated by either varying the amount of current supplied to the field coil or varying the amount that flows through the armature.
DC shunt motors are more commonly used in automotive and industrial applications that require precise speed and torque control. Installing a DC shunt motor is relatively easy. However, special care needs to be given to ensure that the load shaft and motor shaft are properly aligned to prevent putting too much stress on the armature.Learn more about Engine
Some of the symptoms of a bad motor mount include breaking of the mount, thumping noises and stressed components such as wiring connectors, heater and radiator hoses and the exhaust system. In a rear-wheel-drive application with an engine-driven fan, a bad mount can allow the fan to knock the radiator.Full Answer >
An electric starter motor works by generating a heavy electric current at high speeds to turn and start an engine. The starter motor is equipped with a large electric switch that turns on and then off automatically in a short period of time. The electric switch is made to withstand high currents from a car battery and combines with a solenoid valve and electromagnet to start the engine.Full Answer >
An engine rebuild is an extensive repair that requires installing all the internal components of an engine including the oil pump, crankshaft and pistons. Mild rebuilds are usually the result of a damaged internal component while a full-on re-manufactured engine completely refurbishes every part on the block.Full Answer >
Depending on the year and version of the 454, horsepower ratings range from 245 to 450 horsepower. The 454 was available in LS5, LS6 and LS7 versions depending on the vehicle in which it was installed.Full Answer >
