Without going into the math, the change in speed increases the torque the motor can supply. The further the motor speed and supply speed are apart (known as the slip), the greater the torque will be.
Load physically (like putting it in a vehicle) versus it just sitting there has to do with the weight of the load you put on it, as this makes it harder for the motor to spin at higher speeds.
Two reasons could be that the motor was wired incorrectly or the load that the motor is driving is too heavy for the HP of the motor.
on adding load on a dc shunt motor, the amount of current and torque will increase. but terminal voltage will decrease
DC motors use PWM (pulse width modulation), which can easily increase or decrease the power to the motor, thereby increasing or decreasing the motor speed by modulating the width of the pulse. Stepper motors have fixed frequencies, thereby having fixed motor speeds. As a result, the speed of the stepper motor cannot be controlled when the load is increased.
The synchronous speed is 6000 divided by the number of poles for a synchronous motor on 50 Hz, and 5-10% less than that for an induction motor. On a 60 Hz supply these speeds are 20% higher.
When dc motor run full torque at low speed. Armature current is high and field current is set to max to get the torque. When motor is field weaken then temperature decrease at same cooling air flow
The Synchronous motors will operate at a constant speed from noload to fullload. Even it is classified as an AC motor, we have to fed the motor both AC and DC supplies. That we have to supply DC to the Field (Normally Rotor) and AC to the Armature (Normally Stator).
yes, slight modification needed.
no the lose will increase but motor would not heat up and its wiring will be safe this lose will decrease
It is to decrease pressure.
If you're talking about an electric motor, increasing the frequency will increase the speed of rotation of the motor, and decreasing the frequency will decrease the speed of rotation of the motor. The other way of controlling a motor is to control the current; increasing the current increases speed, decreasing current decreases speed.
A Toyota supra motor will fit with slight modifying
try changing plugs and wires
Weak or broken mount.
It's because the same power now have to drive the weight of the armature plus the weight of the load hence the drop in speed. But this is usually short-lived as the armature will eventually draw extra current in order to drive the extra weight.
It may be time for a tune up.
Two reasons could be that the motor was wired incorrectly or the load that the motor is driving is too heavy for the HP of the motor.
whenever the load increases,the current drawn by the motor to do or to fulfill the required energy to the load. so the current will increase generally.Increase in load will cause the full utilization of motor,so speed of rotor will decrease.
