Servo Motors

Servo motors are motors, mostly of permanent magnet synchronous construction, whose position, speed and torque are precisely regulated by encoder feedback and which operate with a servo drive. They are used where fast acceleration and repeatable positioning are required, such as CNC axes, packaging and labeling machines, robot arms and winding systems. The category includes Schneider Electric BCH16 and BCH18, Delta Electronics ECMA and GMT servo motors; ratings such as 400 W, 750 W, 1 kW and 2 kW, rated speeds such as 1500, 2000 and 3000 rpm, and models with and without a brake are available. Select the rated torque and power according to the inertia and speed profile of the load, the rated speed according to the mechanical transmission, the flange and shaft diameter according to the gearbox or coupling connection, the encoder resolution according to the positioning accuracy, and the need for a brake according to the structure of the axis. The product data shows 17, 20 and 23 bit encoders and single-phase 220 V AC and three-phase 380 V AC supplies. It should not be confused with a stepper motor or an induction motor; a servo motor is not connected directly to the mains and operates with the servo drive matched by its manufacturer.

How to choose Servo Motors

Servo motors are motors, mostly of permanent magnet synchronous construction, whose position, speed and torque are precisely regulated by encoder feedback and which operate with a servo drive. They are used where fast acceleration and repeatable positioning are required, such as CNC axes, packaging and labeling machines, robot arms and winding systems.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
