Key Selection Criteria for VFD for Conveyor
When you pick vfd drives for a conveyor, you must think about a few main things. You need to make sure the vfd for conveyor fits your motor, the load type, and how you want to use your system. This helps stop problems and keeps your conveyor running well.
Motor Horsepower and Voltage
Check the motor horsepower before choosing vfd drives. Horsepower shows how much power your motor needs. If the vfd for conveyor is too small, your system will not work right. If it is too big, you waste energy and money. Always pick vfd drives that match the motor’s highest current, especially if your conveyor starts and stops a lot.
Motor horsepower tells you what size vfd drives you need.
Match the vfd for conveyor to the motor’s highest current.
The right size lets vfd drives handle big loads and keeps things safe.
You also need to match the voltage. Most vfd drives work with common voltage levels. The table below shows normal voltage ranges for different conveyor jobs.
Medium-voltage vfd drives often use 660V or 1140V. These voltages help your conveyor stay steady in hard work places.
Tip: Always look at the motor nameplate for horsepower and voltage before picking the right motor and vfd for conveyor.
Load Type and Full Load Amperage
You need to know what kind of load you have. Most conveyors use constant torque loads. This means vfd drives must give strong torque at low speeds and handle heavy loads. The table below shows the difference between constant and variable torque loads.
Conveyors, augers, crushers, and extruders are all constant torque machines. If you use vfd drives for these, you need good overload protection.
You also need to check full load amperage (FLA). You can find this number on the motor nameplate. When you pick vfd drives, match or go a little over the FLA. If you use more than one motor, add all the FLA numbers and add 20-25% for safety. This helps vfd drives handle big power at startup and keeps your conveyor safe.
Find the FLA on the motor nameplate.
Match or go over the FLA when picking vfd drives.
Add extra for safety if you use more than one motor.
Speed Range and Control Needs
You want your conveyor to run at the right speed for your job. Different conveyors need different speed ranges. The table below shows common speed ranges for conveyors.
You need vfd drives that let you change speed easily. This helps you meet your work needs and keeps things steady. Good vfd drives let you control speed well, lower wear, and make things work better.
Control features are important too. You want vfd drives with closed loop control, overload protection, and quick response. These features help your conveyor run smooth and safe. Common control types are V/f control for simple jobs, Vector control for better control, and Direct Torque Control for advanced needs.
Easy speed changes help you work better and safer.
Closed loop control keeps your conveyor at the right speed.
Overload protection stops damage from heavy loads.
Quick response helps your conveyor handle changes fast.
Note: Pick vfd drives with Modbus or Ethernet/IP if you need to connect your conveyor to other systems.
If you focus on these main things, your vfd for conveyor will fit your motor, load, and job needs. This keeps your system working well and saves energy.
