How do you calculate resistance box for slip ring motor?
To calculate the resistance for a slip ring motor, there is an equation that must be solved. This is Torque = S/R. S is the slip of the motor and R is the resistance of the motor.

How a slip ring motor work?
The stator coil is exactly the same as a 3 phase induction motor. The difference being the rotar which has 3 phase wiring in star point or delta connection and also has the sliprings connected to the wiring of the rotor. Brushes are use for the contact between the surpply and the rotor. By controling the current we can control the torgue and speed of the motor. This is done with resistance. Resistance can be greated by means of a resistance bank, liquid resistance or a variable resistance. The basic Idee is: The higher the resistance, low starting current, high torque, high % slip. Motor runs slowlyLow resistance , Higher starting current, lower torgue, lower % slip Motor runs faster.Thus by varing the rotor resistance the motor can be adapted for a spesific load.The motor Are mainly used for Overhead cranes, Elevators in buldings, Pumps under pressure and large fans
What type of test equipment would you use to check the resistance between motor winding?
Ideally megger test is the best test used to check the resistance of motor winding.
How is the resistance of a motor winding expressed?
The resistance of a motor winding is expressed in
What units do you measure resistance in?
Your measure resistance in OHMS ΩOhms.
Why does a motor boat slow to a stop when the motor dies?
Resistance. Water has a lot of resistance.
How do you calculate resistance box for slip ring motor?
To calculate the resistance for a slip ring motor, there is an equation that must be solved. This is Torque = S/R. S is the slip of the motor and R is the resistance of the motor.
Why does my treadmill stop when I step on it?
Your treadmill may stop when you step on it because the motor is not powerful enough to handle the increased weight and resistance. This can cause the motor to overload and shut off as a safety measure.
The will measure resistance only?
The ohmmeter is usually used to measure the resistance of a given wire only.
How do you measure the resistance in a parallel circuit?
You have to measure the voltage, and the current. The resistance is then calculated by using Ohm's Law.
Why meter bridge can't be used to measure low resistance and high resistance?
used to measure low Resistance since it must reach a null.
What is the ohm unit used to measure?
Ohms measure electrical resistance. The resistance in ohms is the voltage divided by the current.
Why does a motor have a bigger resistance than a bulb?
There is no particular reason why a motor should have a bigger resistance than a bulb. A motor's resistance must depend on what current it draws at the particular voltage it was designed to run on. Equally, a bulb's resistance must depend on what current it draws at the particular voltage it was designed to run on. A particular motor may have a higher resistance than one kind of bulb but that same motor may have a lower resistance than another kind of bulb.
What device is used to measure the resistance of a resistor?
You can use a multi-meter to measure resistance. The specific portion of the meter for measuring resistance is called an ohmmeter.
What does the blower resistor do in a 2006 Chevy Express?
The blower resistor controls the speeds of the blower motor Hi-resistance lower motor speed Lo-resistance higher motor speed
