the speed decrease if increasing load..in star connection the speed lower
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.
On an AC motor you basically vary the frequency on a DC you can vary the voltage.
When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.
It sounds like you need a variable speed drill. There was an item on the market a few years ago that you could plug your drill into and control its speed. I haven't seen one lately since most new drills have variable speed built into the drill. On a drill press all you need to do is move the drive belt to the smallest pulley on the motor and the biggest pulley on the drill spindle.
calculate speed drive pulley.
If the load is connected to the motor via belts, you can change the speed the load is turning by changing the pulley sizes. To get the load to slow down, increase the size of the pulley on the load; to get it to speed up, increase the size of the pulley on the motor. To reduce the speed of the motor itself, you'll have to alter the line frequency, which you can't do without a variable frequency drive attached to the motor.

Most are belt driven and have a step down pulley on the motor and the drill. Changing the groove the belt is in changes the speed of the drill. Small groove on the motor and large on the drill will give you the slowest speed.
yes the 3 types of acceleration are increased speed decrease speed or change in direction.
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.
Reduce the size of the pulley on the motor
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.
The speed of the motor depends on load, voltage and current. The speed can be maintain by using a method called Pulse code modulation (PWM). By changing (modulating) the width of the pulse applied to the DC motor we can increase or decrease the amount of power provided to the motor, there by increasing or decreasing the motor speed. mean we have to just change the duty cycle of modulating output.
It depends on the snowblower, belt type and what you arer trying to achieve by making the change. The replacement pulley(s) will have to be the same shaft id as the original to start. Next make sure that there is room inside the snowblower for the new pulley. Thirdly the belt may have to change depending on the pulley size that you choose. There are many different pulley types and sizes available. Be aware of the changes that are made because they can decrease the snow throwing ability and also affect the drive speed and vice versa.
Both. Acceleration is a change in speed.
Acceleration, it can be both increase and decrease in speed. .
