What does the phases on a nameplate of a motor mean?
On a three phase motor, the phases give you direction for how to hook the motor up to make it spin one direction vs. the other. If you hook up such a motor blindly with all three phases, it may spin in the opposite direction you want; to fix, you swap any two of the three phase connections.
What has to occur for an electric motor to spin freely?
In order for an electric motor to spin freely you will have to make sure you have one thing. You have to have the electric current for the motor to run freely.
Why the DC motor is call as synchronous motor?
A 60Hz synchronous motor spins at synchronous speed - if it's a two pole motor it will spin at exactly 1800 rpms. An asynchronous motor will spin at a speed lower than the power supply frequency - a symilar asynchronous motor may spin at 1700 rpms.
What happens if the direction of current at the terminals of a series motor is reversed?
No changes will occur by wiring a 110 volt motor in reverse polarity, rotation will always be the same. Some single phase motors are designed to be reversed ,but that is a function of the relationship of start windings and capacitors and requires some wiring changes in a motor junction box or an end terminal housing, not by just changing the incoming power.
How could you reverse the rotation of the motor?
The motor will spin the direction that the positive lead is on. So if the shaft is pointing towards you, you will need to put the positive lead on the left side to make it turn counter clockwise.
What does the phases on a nameplate of a motor mean?
On a three phase motor, the phases give you direction for how to hook the motor up to make it spin one direction vs. the other. If you hook up such a motor blindly with all three phases, it may spin in the opposite direction you want; to fix, you swap any two of the three phase connections.
How do you calculate the rpm of a motor with a known number of poles and a frequency of 60 Hrtz?
A synchronous motor will spin at the system frequency. 60 Hz translates into 60*60 = 3600 direction changes per minute. If this is a two pole motor (one north and one south), it will spin 1 rotation per direction change. If it is a four pole motor (two north and two south), it will spin 1/2 rotation per direction change. If this is an induction motor, it will spin at a frequency slightly less than an equivalent synchronous motor; this frequency difference is referred to as slip.

What direction does a bullet spin?
Direction of spin is dependent on the direction of the rifling on the inside bore of the barrel. A bullet will spin the same direction as the rifling.
How does a rotocopter spin?
A rotocopter spins by utilizing a motor to rotate the blades around a central axis. The motor powers the rotation of the blades, creating lift and allowing the rotocopter to fly. The pitch of the blades can also be adjusted to control the direction and speed of the spin.
In an electric motor periodically changing the direction of current in the electromagnetic can cause the axle to spin because?
In an electric motor, periodically changing the direction of current in the electromagnet causes the magnetic field to alternate. This changing magnetic field interacts with the permanent magnets on the rotor, creating a rotational force that causes the axle to spin. This process is known as electromagnetic induction.
Does the Earth spin on its axis in the same or opposite direction as the moons orbit?
The direction of the Earth's spin and the direction of the Moon's orbit is the same - counterclockwise
Why won't Maytag Washer spin?
The motor runs in one direction to agitate, in the opposite direction to spin. If the reversing switch is bad, the brake will not release, the tub won't spin, and you may smell the belt getting hot due to slippage.
Which direction do the turbines spin in when the tides come in and out?
Turbines typically spin in the same direction regardless of whether tides are coming in or going out. The direction of spin is determined by the design of the turbine blades and the flow of water.
Do break dancers that spin on their heads spin in the opposite direction when they are south of the Equator?
No, break dancers spinning on their heads do not change direction when they are south of the Equator. The direction of their spin is determined by their personal preference and technique, not their location relative to the Equator.
Describe how the motor continues to spin when connected?
the motor is 2
What causes a motor to spin?
