Is the reducer the same as the governor?
Inequable。 By the difference between the speed reducer and the inverter is the main reducer: variable speed range (ratio), but generally not the stepless speed after many physical and electrical parameters of the motor can be extended, in addition to the speed loss; and by inverter can realize stepless speed regulation, but only limited (speed range speed in 3--100hz), the speed at the many electrical parameters affected, and can not guarantee the original variety of motor pole parameters, and more serious fever.
Frequency converter speed regulation:The frequency converter is used to regulate the speed of the motor (motor) by changing the AC frequency. When the motor speed is reduced by the frequency converter, the energy saving can be achieved. But generally in the range of 0--50hz, variable frequency motor can achieve constant torque speed regulation, in 50--100HZ range to achieve constant power speed control, and are stepless speed regulation, speed range.
3, installation type (reducer and motor, the relative position of the machine, vertical, horizontal).4, transmission ratio and its allowable error.5. Environmental conditions such as ambient temperature, dust concentration, air flow rate and pH, lubrication and cooling conditions (whether circulating water, lubrication stations), as well as restrictions on vibration and noise.6. Requirements for service life, safety and reliability.7. Requirements for size and weight.8 、 requirements for operation and control.9, materials, rough, standard parts, sources and inventory.10. Requirements for lot size, cost and price.11, delivery time.
Speed reducer:Reducer is through the mechanical transmission device to reduce motor (motor) speed, such as the common gear box deceleration, turbine worm deceleration, etc..When the motor speed is adjusted by a reducer, the following information is generally required:1, the type of motor, specifications, speed, power (or torque), start characteristics, short-term overload capacity, inertia, etc..2. Types, specifications, uses, speed, power (or torque) of the working machines. Working system: constant load and variable load, variable load load diagram; starting, braking and short-time overload torque, starting frequency; shock and vibration; rotating direction, motor and reducer shaft connection mode, whether there is radial force and axial force.
