Servo Stepping Motor or Stepping Servo Motor

Stepping motor is open loop motion control unit most of the time. How could we fulfill high speed, closed loop where there is feedback from the motors by using stepping motor instead of servo motor? As you know, an encoder or a sensor is needed for simple stepping motor movement feedback system. UIrobot CANBus stepper controller baud rate reach 112500 bps, that means you run a stepping motor under 16^th micro steppers resolution the speed of the motor could reach 2100rpm. UIrobot CANBus stepper controller is going to open two terminals for sensors. All of this is going to be done to satisfy customer’s servo stepping motor needs.

Customizing the motor
In medium- and high-volume applications,
it is possible to customize the
motor. Most manufacturers offers
customization on the following items.
Shaft Single- or double-sided
Length
Pinions
Winding Resistance
Inductance
Rotor Type of magnets
hybrid air-gap distance
Lead wires Length
Connector
