Brushless DC motors are an advanced option due to their wide speed range, low heat and maintenance-free operation. Stepper Motors offer high torque and smooth low speed operation. Speed is typically controlled by manual operation on the driver or by an external switch, or with an external 0~10 VDC.
Which motor has high speed AC or DC?
Which Motor Is More Powerful: AC or DC? AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.
What is speed in motor?
revolutions per minute

Can you control the speed of a motor?
Thus, the speed of a DC motor can be controlled in three ways: By varying the supply voltage. By varying the flux, and by varying the current through the field winding. By varying the armature voltage, and by varying the armature resistance.
How can the speed of an induction motor be reduced?
An induction motor runs at a speed less than sub synchronous speed. Its speed further reduces further on addition of load. Its speed can be controlled by varying the voltage or by varying the frequency of the supply.
