Brushed DC pancake motors, also called printed armature, axial flux, or servodisc motors, are types of servo motors used for motion control, CNC machinery, automotive systems, printing equipment, and other applications. They are compact, economical, and easy to work with.
Pelonis Technologies, Inc. is a leading supplier of brushed DC pancake motors. We also supply AC motors and other motorized motion control solutions, along with heating and cooling components.
Learn more about our GN Series of brushed pancake motors, their applications, and the models available.
Features & Specifications
Pancake motors get their name from their flat, round, wide shape. They feature a stator with a permanent magnet surrounding an armature that is printed with coil windings and a commutator. Graphite or carbon brushes attached to the armature send DC current to the coil. Current runs radially outward from the center to the armature edge, perpendicular to the axial magnetic field (i.e., axial flux). This produces a force that generates torque and causes the motor to turn.
GN Series features include:
- DC brushed
- Printed armature
- Super-flat construction
- Rare Earth NdFeB magnets for low-temperature operation (to -20°C, -4°F)
- Custom shaft and housing configurations available
- Ironless core
- No cogging - ultra low velocity ripple and smooth running
- Tachometer, encoder, gearbox, and brake options available
- Available as a motor kit
Our brushed DC pancake motors are available in four ranges and three sizes, including armature diameters of 9cm, 12cm, and 16cm.
Every GN series motor is available in a parallel winding (designated LR) or low-resistance configuration. These DC pancake motors are best suited for low battery, low voltage, or higher speed applications.
Applications
Pancake motors are used in many types of servo applications that require compact and responsive motors to achieve high levels of control. Motors in the GN Series can replace older KN-series and N-series servo motors from PMI Kollmorgen.
Applications include, but are not limited to, the following:
- CNC machine equipment
- Agricultural equipment
- Vehicle systems
- Flight simulators
- High-temperature ventilation equipment
- Industrial robotics and automation
- Marine autopilot systems
- Medical mobility devices
- Medical scanners
- Motion control systems and devices
- Printing machinery
- Servo mechanisms
- Test and measurement applications
Markets that benefit these motors include:
- Aerospace and defense
- Automotive
- Industrial automation
- Instrumentation, tests and measurement
- Medical and life sciences
- Logistics
- Offshore marine
- Oil & Gas
- Printing
