UL-listed and CSA Certified high torque and high precision Stepper Motors NEMA23 MST23x up to 3.2Nm

 
A series of step motors that have been designed by JVL for use with the entire range of JVL Step Motor Drivers and Controllers. They are high torque step motors especially made for mini- and microstep operation.
Compared to motor MST23xxx3 this motor is produced in higher quality with less mechanical and electrical tolerances making it more suitable for applications that require repetitive and uniform motors. It also offers better protections against water and use better balls bearings etc. They are prepared for JVL encoder PCB PA0260 with single or absolute multiturn encoder.

 
  • UL recognized and CSA Certified available from NEMA17 to NEMA43
  • Option for rear end magnet encoder from JVL or own encoder PCB.
  • Highest torque density rating in the industry
  • High torque-to-inertia for faster start and stop
  • Rugged design and long life bearings
  • High power, cooler running, rare-earth magnet design
  • Exposed-lamination housing, optimized for high torque and smooth, accurate microstepping
  • Facilities for encoders, double shaft, different shaft types, etc.
 


  • Ground 3mm thread hole for correct EMC shielding
  • High axial and radial shaft load
  • Cost-effective alternative to servo motors
  • Low noise Option for planetary gearhead
  • Standard NEMA23 mounting. 200Step/rev
 
These motors are are recognized to Standard UL-1004-6 for Servo and Stepper Motors, UL 1004-1 Standard for Rotating Electrical Machines, and Canadian CSA Standard C22.2 No. 100-14 for Motors and Generators. Customers are now assured that these JVL stepper meet high-quality standards for electrical safety associated with UL and CSA certifications.
 

Ordering code:

MST23x = Stack size, available: 2 and 4 stack
B = 5 Amp
8 = ø6.35 mm or 43 = ø8 mm.
7 = High torque, UL approved optional
L1 = 100 mm lead wire (4x)
BA = Encoder ready (rear shaft prepared for magnet but no encoder mounted)
5.0 = 5 Amp
UL = UL approved or leave empty for non-UL approved
