YZR2 series electric motors for lifting and metallurgyDetailed product description：

The YZR2 series electric motors for lifting and metallurgy have high overload capacity and mechanical strength, making them the preferred choice for various cranes and metallurgical auxiliary equipment, and also suitable for similar equipment.

The following is a reference clip:

Working conditions:
Power supply voltage 380V, power supply frequency 50HZ
The series resistance of the rotor winding circuit limits the starting current to no more than twice the rated current
Environmental temperature: F-class insulated motor not exceeding 40 ℃, H-class not exceeding 60 ℃
Altitude not exceeding 1000M
Frequent mechanical vibrations and impacts
Frequent starting, braking, and reversing
protection level
Motor casing: IP54
Junction box: IP55
Cooling method IC411
Transmission method
The electric motor adopts coupling or spur gear transmission. When using spur gear transmission, the gear pitch diameter shall not be less than twice the shaft extension diameter.

Installation type of YZR2 series lifting and metallurgical electric motors:

Starting times
Starting level: 6.150.300.600 times (Z)/hour
Conversion of starting times (Z):
The thermal equivalent of one jog (i.e. one incomplete start, during which the speed of the motor does not exceed 1/4 of the rated speed) is 0.25 full starts
The thermal equivalent of one electric brake (braking to 1/3 of the rated speed) is 0.8 full starts
The thermal equivalent of one reversal is 1.8 full starts Typical examples of starting levels are shown in Table 2

Ordering Notice:
When placing an order, it is necessary to specify the product model, rated power, rated voltage, rated frequency, speed range, operating characteristics within this range, and the location of the junction box.
2. If there are special requirements, after consultation between both parties, other pole numbers, structures, and installation types of electric motors can be provided. They can also be equipped with various sensors (speed measuring engines, overspeed switches=encoders, etc.), various brakes (electromagnetic, eddy current), various thermal protection devices, and heating belts.
