Key Features:

Unique ServoDisk armature for enhanced performance
Neodymium Magnet Technology
Ultra-thin compact design for easy integration
Fast acceleration for increased throughput
Wide speed range for flexibility
Zero cogging for smooth operation
Available with or without integrated tachometer

Motor Characteristics:

Rated Values: Includes nominal torque, speed, output, terminal voltage, and current for various models.
Motor Performance: Details peak torque, max peak current, acceleration at peak torque, stall torque, and max load speed.
Intrinsic Motor Constants: Lists torque constant, back EMF constant, viscous damping constant, speed regulation, average friction torque, terminal resistance, armature resistance, armature inductance, mechanical and electrical time constants, and rotor inertia.
Thermal Characteristics: Includes time constants for armature-housing and housing-ambient, resistance values, temperature coefficient of back EMF, and max continuous armature temperature.
Physical Data: Number of magnet poles, commutator bars, admitted shaft load (radial and axial), and weight without extensions.

Operational Guidelines:

Designed for DC current with a form factor of 1.05, uncooled execution, and protection IP 54 at an ambient temperature of +40 °C.
Continuous operation (S1) is feasible at all points of the torque-speed curve, but continuous speed beyond 4000 min^-1 is not advised.
Incremental motion cycle (S3) with a pulse duration of 50 ms and 1% duty cycle is specified.
Stall current should be reduced to approximately 70% if the motor operates with a blocked shaft for more than 20 seconds.

Operational Notes:

For DC current with form factor 1.05, uncooled execution, protection IP 54, ambient temperature +40 °C.
Continuous operation S1 (VDE 530), part 1.4. Motor can be run at all points of the torque-speed curve S1, continuous speed beyond 4000 min^-1 is not recommended.
Incremental motion cycle S3, VDE 530, part 1.4. Pulse duration 50 ms, 1% of duty cycle.
Point of intersection torque-speed curve S1 with torque coordinate at speed zero. Permitted at very low speed < 1 min^-1. If the motor operates with a blocked shaft longer than 20 s, the stall current must be reduced to approximately 70%.
Based upon mounted motors, heat transfer from motor to equipment.
Tachometer must not operate without load, RL,min = 10kΩ.
