When a servo motor driver receives a pulse signal, it rotates a fixed angle of view in a set direction; this is called the "step angle." Its rotation gradually moves from a fixed angle. Angular displacement can be controlled according to the number of control pulses, thus achieving precise positioning. Typically, manufacturers specify rated speed and maximum speed. Low-inertia servo motors are generally rated at 3000 RPM, with a maximum of 5000 RPM. Medium-to-high inertia servo motors are typically rated at 1500-1000 RPM, ideally 2000 or 1500 RPM. In short, high-torque servo motors will have very low maximum speeds. What is the typical speed of a servo motor? What is the maximum speed it can reach?
If the original cycle time is 50 seconds, it can be reduced to less than 48 seconds after the update. This is equivalent to an increase in productivity of over 5% and an indirect energy saving of 5%. In summary, after selecting the servo energy-saving system, the oil pump motor's energy consumption can be reduced by more than 55%, and the project investment cost can generally be recovered in about 12 months. Energy saving is guaranteed. This motor saves more than 50% of electricity.
Can the speed of a servo motor be set arbitrarily? The speed of a servo motor can be set arbitrarily, but the actual setting depends on the specific application and control method. Generally, there are two situations:
1. External analog signal control rate mode
The analog voltage you input is proportional to the motor speed. For example, by default, the main parameter in the controller is that for every 1V of voltage, the motor rotates 500 revolutions per minute, and for a 3V output, it rotates 1500 revolutions per minute. Naturally, the motor's rated power to match the voltage per 1V can be set to 500 kW by default, but can be changed to 80 or 800 kW. The motor speed can be set arbitrarily; simply change the output analog voltage value.
2. Application of Direction Control Mode
At this point, the motor speed is directly proportional to the frequency of the upward pulse. If the controller is set to rotate at 10,000 pulses per second, the motor will rotate in one second. To change the motor speed, simply change the frequency of the upward pulse. The higher the frequency of the upward pulse, the faster the motor speed.
What is the typical speed of a servo motor? What is its maximum speed? Energy saving and environmental protection are also among the development trends of small motor technology, making the development of high-efficiency motors a pressing issue. In recent years, the output density of servo motors has exceeded 1.2kW/kg, with efficiencies reaching 90%-97%. High-speed small motors utilize high-performance magnetic materials and efficient cooling methods to improve output density and efficiency.
