MOTION CONTROL AT THE SPEED OF TECHNOLOGY™
Pancake/Flat Servo Motors
Pancake or Flat Motors are available from both maxon and Kollmorgen. Electromate supplies maxon brushless pancake motors throughout Canada’s four distinct industrial regions: the Atlantic Provinces, Central Canada, the Prairies, and the West Coast.
maxon EC and EC-i Brushless Pancake Motors
When space is at a premium, maxon Brushless Pancake Motors are the solution.
The electronically commutated maxon EC flat motors are particularly noteworthy for their excellent torque handling characteristics, high performance, extremely wide speed range and, of course, their unsurpassed service life.
These compact and extremely powerful EC flat motors are ideal if space is limited. With an operating range of 0.2 - 600 Watt, the EC Flat Motor Series are external rotor motors that run very quietly.

Kollmorgen ServoDisc™ Pancake Motors
ServoDisc™ Pancake Motors from Kollmorgen differ from conventional brush DC servomotors in their unique slotless disc armature.
This design delivers a concentrated level of performance in both incremental motion and continuous speed applications that conventional ironcore motor designs can’t achieve.
ServoDisc™ motor technology offers a slotless, ironless design with zero cogging for precision at all speed ranges, including single-digit rpms. The flat, thin armature provides for a compact form factor while enabling quick acceleration, deceleration and direction changes.
The low-voltage DC design allows operation with simple drive electronics and a basic, convenient power source including battery power.
Kollmorgen Pancake Motor Features:
- Common modification options include application-specific mountings and connectors, gearboxes and feedback devices, sealing and ruggedization, materials and coatings, and electromagnetic configurations
- Co-engineered modifications available to suit demanding applications such as life-critical medical devices, military equipment, semiconductor wafer manufacturing and delicate material handling
- A broad torque range, from 0.12 N-m to 33 N-m, accommodates a wide variety of applications
- Torque is nearly instantaneous from start of rotation, with a flat torque curve throughout the speed range
- Long brush life, up to 1.2 billion revolutions or more
- Absolutely zero cogging, even at very low rpms
- High acceleration, from 0 to 4,000 rpm in under 60 degrees of rotation and as little as 10 milliseconds
- Peak torque of up to 10 times continuous torque without risk of demagnetization
- Small axial size is ideal for portable equipment and machines with tight clearances
