What is a rocker arm in a DC motor and what will happen if the rocker arm connections are changed?
A rocker arm holds a carbon brush. In other words it is a carbon brush holder. Changing over the rocker arm connections is the same as changing over the armature connections and will make a DC motor turn in the reverse direction assuming that the magnetic orientation of the motor's field stays the same.
More detailDC motor having a field winding
If the stator's field is created by a field winding and that winding's connections are changed over at the same time as the armature's connections are changed over, then the DC motor's direction of rotation will be the same as before.
If the stator's field is created by a field winding and that winding's connections are not changed over at the same time as the the armature's connections are changed over, then the DC motor will turn in the reverse direction.
DC Motor having a field created by a permanent magnet
If the stator's magnetic field is created by a permanent magnet and the orientation of that magnet is reversed at the same time that the armature connections are changed over, then the DC motor's direction of rotation will be the same as before.
If the stator's magnetic field is created by a permanent magnet and the orientation of that magnet is not reversed at the same time as the armature connections are changed over, then the DC motor will turn in the reverse direction.

How do you change a direction of a motor?
DC motor: Switch your leads. AC single phase motor: Direction cannot be changed. The motor will run the same direction regardless of how your leads are terminated. AC 3 phase motor: Switch any two leads.
Why is a synchronous speed motor considered a constant speed motor?
synchronous motor is a constant speed motor because it will only run at a synchronous speed or not at all.the speed can be changed by changiing the frequency only ns=120f/p

How do you reverse the rotation of shunt motor?
Reverse the armature connections or the field connections, but not both.
If you can Chang winding 50hz to 60hz?
If you have the motor rewound you could possibly have it changed. You can run some 50 hz motors on a 60 hz system but there are no guarantees. The motor will run faster and there is a chance it will overheat. There is no way to change the field connections of a motor to accomplish this. Best bet is to just purchase the correct motor.
What is the best place to get your motor oil changed?
There are many mechanic stores and garages where a person can get motor oil changed for a vehicle. An example of a place where motor can be changed is Midas.

What is a rocker?
you are probably refering to a rocker arm. In a pushrod motor the rocker are opens the valves. A rod rides on the camshaft and as the lobes on it come around the rod pushes up on the rocker are which does exactly that, rocks the same as the rocker on a rocking chair . The rod pushes up on the rocker which then pushes down on the valve, opening it.
What will happen if supply terminals of dc shunt motor interchange?
it will run in same direction because flux and armature current both will be changed wih plarity.
