What are wound field motors and where are they applied?
02/08/2018· Brushed DC motors are generally available in two types, depending on the construction of the stator: permanent magnet or wound field. Both motor types use current and windings to produce a magnetic field in the rotor, but they differ in how the stator magnetic field is produced: via permanent magnets inside the stator or with electromagnetic windings.Slip ring motors | up to 8000 kW 13800 V,They are used in various industries such as cement, paper, water or steel and are employed there as drives for mills, compressors, blowers, refiners, shredders, etc. MENZEL slip ring motors, also called wound rotor motors, are available in all current motor cooling and protection types for low-voltage from 75 kW as well as medium and high voltage up to 15000 kW.Autogenous mills, semi-autogenous mills and ball mills for,,either wound rotor induction motors or synchronous motors can be used. Induction motors Wound rotor induction motors are usually equipped with starters for a controlled ramp up of mill speed with modest inrush currents. Motor speeds usually require the appli-cation of a speed reducer. Synchronous motors Synchronous motors are usually of the low,Drive Solutions for the Global Mining Industry,mills, fans, and pumps use VFDs to provide high power and speed control, as well as generate signifi cant associated energy and maintenance savings. • The TMdrive®-10/30/50/70 family of drives and TMEIC motors are also well-suited for mine hoist applications. • Drives are useful in soft starting large mill motors. Motor life is extended by eliminating inrush currents. Low currents at,Brushed DC electric motor - Wikipedia,Since the series-wound DC motor develops its highest torque at low speed, it is often used in traction applications such as electric locomotives, and trams. Another application is starter motors for petrol and small diesel engines. Series motors must never be used in applications where the drive can fail (such as belt drives). As the motor accelerates, the armature (and hence field) current,Presentation wound rotor ppt - SlideShare,20/02/2014· Terms used in Wound Rotor Slip..

ut a ring on it
In a wound-rotor AC induction motor, the slip-rings are not used to carry electrical current. Instead, they are used to connect an external resistance into the rotor windings. In a three-phase motor, three slip-rings are used – one connected to each rotor winding phase. The slip rings are tightly mounted on the shaft by insulated supports so that they rotate at the same speed. The brushes,A TECHNOLOGICAL — — PIONEER,The permanent magnet-excited rotor is used for this motor to eliminate an external excitation device. Such devices take up a lot of space, create additional losses, and require high maintenance efforts. There are two rotor concepts for permanent magnet-excited rotors: surface magnets and embedded magnets. Rotors with surface magnets are characterised by a simple design. The magnets are glued,Slip ring motors | up to 8000 kW 13800 V,They are used in various industries such as cement, paper, water or steel and are employed there as drives for mills, compressors, blowers, refiners, shredders, etc. MENZEL slip ring motors, also called wound rotor motors, are available in all current motor cooling and protection types for low-voltage from 75 kW as well as medium and high voltage up to 15000 kW.Synchronous motor drive for rubber mills: With special,,Synchronous motor drive for rubber mills: With special reference to dynamic braking control for safety stopping Abstract: Since wound-rotor induction motors with clutch brakes have been very commonly used for this application, a review of the operating conditions and safety requirements is given, in order to show why synchronous motors without clutches may be used for the same application.Getting in Control - Electrical Products & Solutions,23/11/2020· Take a cement plant, for example. There, equipment such as large grinding mills that need to drive high torque load demands at low speeds.

The synchronous motor doesn’t rely on induction current for working. In these motors, unlike induction motor, multiphase AC electromagnets are present on the stator, which produces a rotating magnetic- field.Here rotor is of a permanent magnet which gets synced with the rotating magnetic- field and rotates in synchronous to the frequency of current applied to it.Types of AC Motors and DC Motors - Engineering Tutorial,07/03/2016· A permanent-magnet motor does not have a field winding on the stator frame, instead relying on permanent magnets to provide the magnetic field against which the rotor field interacts to produce torque. Compensating windings in series with the armature may be used on large motors to improve commutation under load. Because this field is fixed, it cannot be adjusted for speed control.,,,
