Series wound DC motors are best for applications that require high startup torque, without the need for speed regulation. Like a shunt motor, as a load is applied to a DC series motor, the motor speed decreases, which reduces the back EMF and increases the net voltage.
Which of the following motor is used where high starting torque?
1. Which of the following motor is used where high starting torque and wide speed range control is required? Explanation: DC series motor gives the maximum starting torque at starting.
How do you increase the torque of a DC motor?
To increase the torque … that a bit harder. All you can do, electrically (as you can do it mechanically via gears), is to reduce the source impedance to maximise the current that can be delivered for a given stator impedance. Rewind it with more turns of thinner wire.
Which DC motor has maximum self loading property?
Which DC motor has got maximum self-loading property? Explanation: A differentially compound DC motor, flux reduces so sharply at small increase in load at higher values of load.
Which is a better method to control motor speed?
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.
Which type of starter motor generates the highest torque at low rpm?
Excellent torque characteristics at low speeds
Stepper motors have maximum torque at low speeds (less than 2000 rpm), making them suitable for applications that need low speed with high precision. Normal DC motors and servo motors do not have much torque at low speeds.
Which motor is used in tramway?
Dc motor (Ma) and induction motor (Mc) are currently manufactured and used in 105 N tram drive, their parameters are available. Dc motor (Mb), brushless motor (Me) and slip-ring motor (Md) pa- rameters have been determined by analysis.
Which is proportional to the torque in DC motor?
For DC Machine, torque is directly proportional to armature current and flux. In dc shunt motors, flux is constant (not dependent on armature current). Hence torque is proportional to armature current.
