AKM Series Servo Motors

The AKM series servo motors offer a wide range of mounting, connectivity, feedback and other options. These motors offer superb flexibility to meet application needs with:

8 frame sizes (40 to 260 mm)
28 frame-stack length combinations
117 ‘standard’ windings

AKM Features

Torque – 0.16 to 180 N-m continuous stall torque (1.4 to 1590 lb-in) in 28 frame/stack combinations. Specific torques are often available from multiple frame sizes to optimise mounting and inertia-matching capabilities.

Speed – Speeds to 8000 rpm meet high-speed application requirements. Windings tailored to lower speeds are also available.

Voltage – AKM series servo motors can be applied to all standard global voltages. Windings are specifically tailored to 75 Vdc, 120, 240, 400 and 480 Vac.

Mounting – Multiple mounting standards are available to meet common European, North American, and Japanese standards.

Feedback – AKM motors include resolver, encoder (commutating), Sine-Absolute encoder or Kollmorgen’s SFD (Smart Feedback Device) feedback options to meet specific application requirements.

Smoothness – Smooth performance results from low-cog, low-harmonic distortion magnetic designs.

Connectivity – Rugged, rotatable IP65 connectors or low-cost IP20 Molex plugs are both available to provide flexibility. Single connectors/plugs (combined power and feedback) are also available to minimise motor and cable costs (SFD only).

Thermal – Windings are rated conservatively for a 100°C rise over a 40°C ambient while using 155°C (class F) insulation materials. Motors meet applicable cURus and CE requirements and include thermistors. Thermal ratings for 60°C rise are also provided to meet the needs of specific applications.
