Three-phase rock crusher AC motors operate with extra-high starting torque and operate at low speeds to power cone, jaw, and roller rock crushers, impactors, and pulverizers. They have a totally enclosed fan-cooled (TEFC) enclosure with an external fan in a protective shroud to blow cooling air over the motor to protect against dust and water jets.
Voltage spike damage occurs more often in motors controlled by variable frequency drives. Troubleshooting the most typical winding problems of three phase electric motors. These problems are all caused by in-plant faults that require correction. A replacement motor can fail sometimes immediately if the in-plant problem isn't corrected.
DC (direct current) motors generally have higher starting torque compared to AC (alternating current) motors. The starting torque of a motor is crucial for applications where the load initially resists motion, such as in conveyors, crushers, and other heavy-duty machinery. In a DC motor, the torque is produced by the interaction of magnetic ...

As grids have been evolving towards more complex structures and consumer's demand for reliable, secure electricity increases, the quality of power is more critical ever than before to meet these expectations. In addition, electrical equipment works in defined certain limits of voltage and frequency while operating in these tolerance limits.
Best suited for secondary crushing applications, cone crushers are designed to crush pre-sized materials, usually 100mm, 150mm or 200mm, depending on the size of the crusher. Cone crushers can form finished products down to 12mm or less. Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, …
Impact Crusher Working Principle. Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them. Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact would be dropping a rock onto a steel plate …

A not uncommon thing to happen with crushers is that someone bought a "crusher duty" motor and the old ones were not, they were basic Design B motors (in terms of torque-speed curves). Some crusher motors are built as Design A, which results in higher torque at a similar step change in speed. So the full load torque and speed is …
