Separate Controller and Motor – with Closed-Loop

PRESS release: November 2021

Birkerød, Denmark - JVL A/S, one of the world’s leading producers in the field of integrated servo and stepper motors, is announcing that their stepper controllers SMC66 and SMC85 are now capable of real closed-loop with a separate motor.
  • Performance equal to our integrated ServoStep™ motors – speed up to 3000 RPM
  • Ideal for extreme temperatures in the range -40 to +105°C
  • To be used where the smallest possible motor is needed

Closed-loop with a wide range of encoders
The new closed-loop feature for separate controllers and motors with encoder, can be used with most SSI encoders (non-Gray coded) and incremental quadrature 4096 CPR (1024 PPR) encoders and the list of applicable encoders is expanding according to requests.
This allows you to use closed-loop operation with almost any step motor mounted with an encoder using our controllers. 

Special Temperatures and Compact Sizes
The non-integrated solution has identical performance to our market leading integrated closed-loop stepper motors ServoStep™ but is to be used when the temperature range is outside the working range of our integrated motors – or if an extremely compact solution is required.
Used with our PA0260 encoder the operating temperature range is -40 to +105°C.
NEMA 17 to 43 motors with built-in incremental encoders or absolute multiturn encoders are available from JVL.
JVL also offers ready-made cables for fast and easy connection of motor, encoder and controller.
