Special electric motors manufactured by a Russian company VEMZ The ADHR series (asynchronous low-voltage electric motors with frequency control) are designed to operate mechanisms with a fan characteristic of up to 1400 kW, voltage up to 690 V (pumps, fans, smoke pumps, conveyors, etc.). The connection of the motors to the drive mechanism is carried out by means of elastic couplings. The engines are made on plastic-lubricated rolling bearings, and can be equipped with SKF or FAG bearings. Insulating materials of the stator winding of the heat resistance class not lower than "F" with a temperature of use at the level of class "B". The motors are equipped with temperature control sensors for the winding, stator core and bearing assemblies. In agreement with the customer, it is possible to install current-insulated bearing assemblies.
Advantages of electric motors manufactured by a Russian company VEMZ ADHR series:
- Higher energy performance;
- Lower temperatures of the active parts in the operating mode, which increases the reliability and durability of the insulation of the stator winding and the motor as a whole;
- A more rigid and durable frame, which increases the ability of the engine to withstand external vibrations, shock loads;
- A more efficient lubrication replenishment and discharge system;
- The ability to extract used grease without stopping the engine;
- The rotor winding is aluminum, welded, has greater strength and reliability compared to the cast winding, which is prone to cracking;
- More modern temperature control sensors and a more convenient connection point to them (plug connector);
- A more reliable design for installing and fixing the output ends of the stator winding, which is very important for engines of this series. In addition, the lead ends are made of class "H" wire (made of organosilicon rubber).
The engines of the ADCR series are used to drive the mechanisms of pumping, fan and conveyor equipment.
