Low inertia dc servo motor M66 series The M66CE is a high performance low inertia dc servo motor, providing up to 30W output power and offers smooth operation over a wide speed range. The M66CE motor incorporates a skewed ironless rotor thereby ensuring linear speed and torque characteristic combined with rapid acceleration and reversal capabilities. The type M66CT includes an integral dc tachogenerator for optimum velocity control using analogue control techniques while M66CI series is provided with an integral dual track incremental encoder for use with digital control circuits.

dc servo motor with parking brake M66DB series The M66DB is a low inertia, ironless rotor dc servo motor which is equipped with a ‘power-off’ parking brake to provide a static holding torque to resist movement under unbalanced load conditions when the motor/brake assembly is de- energised. Additionally the brake may be used in dynamic conditions to arrest motion although increased wear will then occur. When the brake is energised the motor is free to rotate and may be controlled to provide a very wide speed range with minimal cogging, even at low speed, due to it’s ironless rotor construction. The motor is equipped with long-life carbon brushes which are suitable for electronic speed control by either linear or PWM servo amplifier systems. Dimensions: mm.
