How to Select The Right SEW Motor
SEW motor belongs to a small motor power, its power range is 0.12-200KW and the torque range is 0-53000NM. How to choose the right motor for you? You mainly consider from three aspects :the power and speed ratio, reducer system, thinning reducer block.
Determine The Power and Speed Ratio of the Gear Motor (Output Speed)
The motor power and speed ratio (output speed) need engineers to design according to the motion mode of our equipment.The lifting motion of the reducer is different from the horizontal transport.
The lifting motion needs to calculate the power and speed by raising the line speed, sprocket rolling diameter, lifting weight, speed and other parameters.When the equipment does horizontal movement, the engineer will calculate the power and speed ratio by the horizontal motion linear speed, sprocket rolling diameter, workpiece weight, friction coefficient acceleration and other parameters.
These parameters are what engineers need to consider, without these parameters, there is no way to start to design a gearmotor.
Determine The Type of The Reducer Motor
Due to the space of the equipment is different, we need to choose the reducer according to the space of the equipment, SEW Gearmotors can be divided into two main categories and five series.
According to the position of the shaft, the motor can be divided into front and side shafts. The shaft of the front axle motor is a line or parallel to the motor, which takes up more space when used, but their price is cheaper and their efficiency is higher. The side-shaft motor can be mounted against the assembly line, which can save space. But they're more expensive,suitable for use in some drive mixing or pleasure vehicles .
Refine the SEW Reducer accessories
In addition to knowing the motor power, speed ratio and type, you still can't choose a specific motor in the face of a certain model, because you still need to determine the details. Just like whether you need a hollow shaft or a solid shaft for the motor, foot-mounted flanges-mounted? Motor need not with or without a brake? The voltage in different countries will also be different, and the right voltage can be selected to maximize the efficiency of the motor. The following is a motor R97DRN100L4/BE5 as an example, a brief introduction to the purchase of motor need to provide some data.
