LOAD TEST ON INDUCTION MOTOR Bhagwant University. Slip-ring motors are used in applications requiring high starting torque or low starting current. These motors provide maximum availability, and are especially recommended for heavy load inertia applications like mill drives or situations where network conditions are weak., Slip ring induction motors from MENZEL are extremely efficient, reliable, and robust convince with their high mechanical load capacity. MENZEL slip ring 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 15,000 kW..

Slip-ring motors are used in applications requiring high starting torque or low starting current. These motors provide maximum availability, and are especially recommended for heavy load inertia applications like mill drives or situations where network conditions are weak. Generally, induction motor provides low starting torque as compared to D.C series motors but this disadvantages of the induction motor can be overcome by slip ring induction motor. >> A slip ring is also used in applications where the load require good speed control .

General Purpose Slip-Ring Induction Motors The catalogue covers slip-ring induction motors called also wound rotor induction motors that are applied to start a high inertia load or a load that requires a very high starting torque across the full speed range. type of motors are called slip ring motors. Sectional view of the full induction motor is shown in Fig. 8 Some more parts, which are required to complete the constructional details of an induction motor, are: • Two end-flanges to support the two bearings, one at the driving-end and the other at the non driving-end, where the driving end will have the shaft extension. • Two sets of bearings

Squirrel Cage Induction Motor vs Slip Ring Induction Motor by ADMIN В· Published June 16, 2015 В· Updated January 1, 2018 Comparison of Squirrel cage induction motor with slip ring induction motor (Wound Rotor Induction Motor) is listed in the below table: Slip ring induction motors are used in various industry segments like Cement, Metals & water and Waste water treatment, etc. Traditionally, speed control of slip ring induction motor was achieved through varying the rotor resistance.

COMMON SLIP-RING INDUCTION MOTOR FAULTS There are various faults in induction motors. This section describes different faults. The different faults classifications are based on the internal and external type of major faults occurring in the machine. The internal faults are placed under mechanical fault and electrical fault categories. While the external fault placed under electrical In slip ring induction motor, the rotor conductors are brought out with slip ring and brush and these conductors can be externally connected to extra resistance, autotransformer or star-delta for suitable starting and maximum torque at start.
