SEM Servomotors
 

SEM is a leading designer, manufacturer and supplier of AC and DC permanent magnet servomotors to system integrators and large OEMs worldwide.  In-house SEM produces several standard series of servomotors in the torque range of 0.2 to 95 Nm (1.9 to 840 lb.in) and also has the capability to design and manufacture customer specific motors.

  Products:        
  AC Brushless Servomotors      
 
Synchronous Type
   
      Compact Motors    
    HDM --> More Info and Specs
HDM series of compact, high power density servomotors provides high dynamic performance with the advantage of small compact size and light weight. Designed for applications where space is at a premium and reduced motor weight is beneficial. HDM motors are available in 4 frame sizes with a stall torque range of 0.48 to 25 Nm.
      Low Inertia Motors    
    HDM--> More Info and Specs
HDM series of compact, high power density servomotors provides high dynamic performance with the advantage of small compact size and light weight. Designed for applications where space is at a premium and reduced motor weight is beneficial. HDM motors are available in 4 frame sizes with a stall torque range of 0.48 to 25 Nm.
   
    HR/HRS --> More Info and Specs
HR/HRS series of low inertia motors provides high dynamic performance across a wide speed and torque range. HR/HRS motors are available in 6 frame sizes with a stall torque range of 0.2 to 67 Nm.
      High Inertia Motors    
    HJ --> More Info and Specs
HJ series of AC servomotors have high inertia rotors along with larger than standard shafts and bearings to provide ultra smooth operation with minimal vibration and resonance when coupled to high inertial loads. Ideally suited for machine tool axis or for applications where the reflected inertia is high. HJ motors are available in 5 frame sizes with a stall torque range of 3 to 67 Nm.
 

Asynchronous Servomotors

     
  Spindle Motors  
   
      Standard Shaft Asynchronous Spindle Motors
ASM Asynchronous Spindle Motors are available standard bearings or with optional high precision spindle bearings for high speed operation
 
      Hollow Shaft Asynchronous Spindle Motors
ASM hollow shaft Asynchronous Spindle motors allow for the coolant path to pass through the motor shaft.
   
  Custom Design Motors        
   

With prototyping, pre-production and full in house manufacturing capability, SEM can design a motor to suit your specific needs.

Using the latest Permanent Magnet, Switched Reluctance or Asynchronous motor technology, our experienced design team can optimise motor performance and cost to provide the right solut

  Legacy Products and Spares  
      MT DC Brushed Motors  
       

Dating back as early as 1974, SEM produced DC brushed servomotors in a range of 4 frame sizes: These motors are now legacy products and have either been withdrawn completely from production or reduced to service production levels.

Motor and spare parts availability:

MT22 – Complete service motors and full spares availability.
MT30 - Complete service motors and full spares availability.
MTS30 - Complete service motors and full spares availability.
MT40 – Limited spare parts availability only.
MT52 – Limited spare parts availability only.
DBMT52 – Limited spare parts availability only

 
      Spares  
       

A comprehensive range of spare parts and service kits are available for most SEM current and legacy products.

To ensure parts are correctly specified SEM requires a motor serial number to accompany any request for major items such as complete motors, armatures, rotors or stators. This may also be required for optional items such as brakes, connectors, adapters, enclosing covers etc.

 


All SEM servomotors are CE marked and manufactured to ISO 9001:2000 standards, with UL approval on request.
Recently introduced, the HDM series of compact servomotors offers high torque and dynamic performance in a small package. Full information is available through the product section on SEM’s website; www.sem.co.uk .
