The 23 frame stepper motor with metal ring connector, designated the 23HT18C, is available in single, 2-, 3- and 4-stack versions. The sealed aluminium terminal block adds around 32 mm to the length of the motor with an internal 6-way screw terminal strip connector for unipolar, bipolar parallel or series wiring. The metal ring connector is a Souriau UT series, size 12 bayonet type which is suited to best-practise electrical shielding and offers IP67 protection as standard or IP68 on request. The durable and rugged connector can be used in environmentally demanding applications or where a neat and aesthetic machine design is of high importance. Mating connectors are supplied and complete lead sets can be included if required.
The alternative cable gland option uses a standard M18 industrial grade gland with a neoprene cable sealing insert and an O-ring seal on the external thread, typically offering IP68 protection up to 5 bar. Mclennan can deliver motors wired with cables to length or cables and components supplied separately.
The 200 steps/rev motor is available in current ratings of 1A, 2A and 3A per phase (5A/phase for the 4-stack version), and thanks to its neodymium magnet system will deliver a holding torque from 0.39 Nm to 2 Nm with usable speeds up to 10000 steps per second.
The 34 frame variant, the 34HT18C is available in single, 2- and 3-stack versions for a holding torque to 7.35 Nm.
Using its own in-house design and manufacturing capability, Mclennan are able to provide complete mechatronic solutions based around the new 23HT18C range that include custom mechanics, gearboxes and power train components. A wide selection of stepper drives and motion controls are also available and the scope of supply can include full EMC testing using the Company’s own onsite test facilities.
