Apr 03 2018 The rotor position is sensed using Hall Effect sensors that are embedded in the stator. Most BLDC motors have three Hall sensors embedded in the stator on the non driving End of the motor. Whenever the rotor magnetic poles pass near the Hall sensors they generate a high or low signal which indicates that N or S pole is passing near the Sensors.
The twin rows of stator knives and screen in the ZTTS enable it to take the tyre shreds down to a any required size > 20 mm. The unique machine design combined with the variable cutting gap create an optimal separation of rubber and steel fractions.

It’s true there are low cost counterfeit manufacturers who can supply parts that look the same and will fit your machine. While there are many ways to cut corners on the production of spare parts to reduce manufacturing costs there are definite consequences. Our patented NextSTEP stator/rotor is the market leading flotation mechanism to
Aug 01 2016 The partly enlarged air gap length made by unequal rotor out diameter and stator core cutting is introduced in interior permanent magnet brushless DC motor IPM BLDC . Adding holes in rotor core is used for good solution that both the cogging torque and the torque ripple reduction is extremely low 3 .

The THM CM Cutting Mill is the right choice for cutting of pre size reduced parts into smaller granules. Size reduction takes place by a wear resistance rotor with rotating knives which are cutting against stator knives. The final granule size is determined by the size of the screen holes.
Jul 30 2020 The brushless nature of the motor means that the rotor and stator components never come in direct contact with each other reducing energy lost to friction and the generation of waste heat. The use of AC signals also greatly reduces the power output of a permanent magnet motor by combining the effects of magnetic attraction and repulsion the
Nov 01 2021 The absence of a stator core allows us to put two identical rotors facing each other on either side of the stator with each rotor carrying powerful permanent magnets. This arrangement creates a
Mar 29 2022 Coffee waste is a bio waste but it produces a lot of methane which is about 32 times more potent than CO2. So what we do here is simply extend the life cycle by repurposing it for alternate use.
The transformation coefficient of the solid rotor impedance to the stator winding is expressed as ktr = m 1 N kω 2 m2 N2kω2 2 = 2m N kω1 2 p 3 where m1 is the number of stator phases m2 the number of rotor phases and is equal to 2p. σ1 is the number of turns in series per phase of stator winding σ2 is the number of turns in series per
