Can you run a servo motor without a drive?
Re: Is it possible to run a ac servo motor without the encod if you do not care about exact positioning, and only ‘close speed’, yes, you can do this.
What is the use of servo drive?
In essence, the role of the servo drive is to translate low power command signals from the controller into high power voltage and current to the motor. Depending on the application, the servo drive can regulate and properly coordinate the motor’s desired position, speed, torque, etc.
How do you size a servo drive?
Divide the motor speed by the required speed and round down to get a starting gear ratio. Then divide the required torque by the gear ratio to find the new required torque. This will narrow the choices down to just a couple of motors. Next, find a motor with an acceptable inertia ratio.
How strong of a servo do I need?
It is important to choose a servo which is strong enough to handle the size and weight of your car. A normal 1/10 buggy or short course/stadium truck ideally needs a torque of around 10kg. A 1/10 on-road car will be alright with a little less, so around 8kg will be enough.
How to choose a drive for a servo system?
Sizing a motor for a servo application requires evaluating the move profile and torque requirements to determine the mechanical demands of the system, such as maximum velocity and acceleration, RMS and peak torque values, and load-to-motor inertia match. Once the motor is chosen, the next step is to select a drive.
What is the power transmission mechanism of a servo drive?
Servomotor Power transmission mechanism Servo drive Feedback signals Feedback signals Target values Motor power signals Controller (1) Command section (2) Control section Controls the motor according to commands. Outputs command signals for operation. (3) Drive and detection section
How is regenerative energy used in a servo drive?
Regenerative energy is the energy generated by a motor when the motor operates. A servo drive uses internal regenerative processing circuits to absorb the regenerative energy generated by a motor when the motor decelerates to prevent the DC voltage from increasing. If the regenerative energy from the motor is too large, an overvoltage can occur.
What kind of loop does a servo drive have?
While all servo drives incorporate a torque control loop and a velocity control loop, only digital drives can provide position control. Servo drives often have a multi-loop structure, with the current loop nested inside the velocity loop, which is nested inside the position loop.
