STYB series mining explosion-proof permanent magnet 3-phase synchronous electric drum STYB90-2.5-6.30X800(660) STYB110-2.5-6.30X800(660) STYB132-2.5-6.30X800(660) STYB160-2.5-6.30X800(660)

1 Overview
This series of products complies with the technical requirements of 0E.512.021-2022 "Technical Conditions for Mining Explosion proof Three phase Permanent Magnet Synchronous Electric Rollers", and the efficiency refers to the Level 1 energy efficiency standard of GB30253-2013 "Energy Efficiency Limit Values and Energy Efficiency Grades for Permanent Magnet Synchronous Motors".
This series of products integrates the drive drum of the conveyor with the permanent magnet motor into one unit, designed as a drive device with an outer rotor and an inner stator. The structure is compact, occupying less space and saving installation space. The belt is directly driven by an electric drum, without any intermediate transmission links, which improves system reliability and efficiency, saves energy and consumption, has low operating costs, good economic benefits, and is easy to maintain with extremely high maintenance volume, saving maintenance costs.
The electric rolling mill complies with the relevant provisions of GB 3836.1 and GB 3836.2, and has obtained an explosion-proof certificate issued by a nationally recognized inspection unit The mining product safety mark certificate issued by the National Mining Product Safety Mark Center shall be manufactured in accordance with the approved drawings and technical documents through the prescribed procedures.

2 Product Features
a) The permanent magnet synchronous electric drum bearing adopts domestically produced self-aligning roller bearings.
b) The permanent magnet synchronous electric roller adopts flame-retardant rubber coating to reduce belt slippage, and has excellent wear resistance and grip. Its flame-retardant and anti-static properties meet the requirements of MT962 standard.
c) The stator winding of the permanent magnet synchronous electric drum adopts the insulation process of "vacuum pressure impregnation", which has excellent insulation and corona resistance, good thermal conductivity, high mechanical strength, and good moisture-proof, anti fouling and waterproof performance. The temperature rise of the motor stator winding is not more than 60K.
d) The permanent magnet synchronous electric drum adopts neodymium iron boron sintered permanent magnets with negative temperature characteristics, that is, its remanence density and coercivity both increase with decreasing temperature, which can adapt to extreme low-temperature environments on site; Permanent magnet adopts advanced high-temperature resistant technology to ensure no demagnetization during normal operation and overload conditions; Permanent magnets have sufficient mechanical strength to withstand vibrations during on-site operation without demagnetization.
e) The permanent magnet synchronous electric drum adopts an external rotor direct drive permanent magnet synchronous motor, and the shaft is fixed on the support seat; There are bearings at both ends of the machine shaft, which are connected to the front and rear covers respectively; There is an outer rotor casing between the front and rear covers; There are permanent magnets inside the casing; There are spokes on the shaft, and front and rear water pressure plates are set at both ends of the spokes. There are inlet and outlet holes in the shaft between adjacent spokes; Radiant plate Install stator core and winding on top; There is a temperature measuring platinum thermistor at the end of the stator winding.
