optional integrated motor base allows installation of the crusher drive motor directly to the back of the crusher. The motor moves in sync with the crusher so the V-belt life is enhanced and alignment and tensioning are always perfect. An optional feed chute is engineered for uninterrupted material flow from the feeder into the crusher.
Nov 09, 2017 Mechanical removal, installation and methods. Removing a failed bearing safely and properly is step one. Pullers and presses designed for that purpose are the best options for three reasons safety, saving time and minimizing the damage to the shaft and housing during the process.
HPK-Series asynchronous motors have a mounting pilot for aligning the motor on a machine. The installation must comply with all local regulations and use of equipment and installation practices that promote electromagnetic compatibility and safety. The motor shaft and the load shaft must be parallel and pulleys aligned.

An AC motor is reversed by reversing the connections of one leg on the three phase power line or by reversing the leads on a single phase power line. Reverse Torque A torque created by harmonics in a three phase motor and often resulting in a motor running at a reduced speed. Normally the forces of the revolving field all rotate in the same ...
The end of the motor is defined in the IEC-standard as follows The D-end is normally the drive end of the motor. The N-end is normally the non-drive end of the motor. About Motors Note that in this handbook we will focus on asynchronous 3-phase electrical motors only. Terminal box Cooling fan Drive shaft Stator windings Rotor Stator D ...
The primary concern here is that improper installation can introduce the motor terminals to much higher voltages than the insulation is design to accommodate. In addition, the path of least resistance to common mode current may well be the motor bearing, which generally shortens bearing life.
Three Phase AC supply Around 80 of energy conversion from electrical to mechanical is carried out by 3-phase induction motors. First choice for most industrial drives. Only when load characteristic does not match with mechanical or electrical characteristics of motor, selection is
