HDD/ICM 14J - Data sheet

Product catalog summary

Overview: This document is a technical data sheet for the HDD/ICM 14J series motors, detailing their specifications, mechanical and electrical data, and operational guidelines.

Electric Data: The motors are designed to operate at a suitable rail voltage of 3000 rpm. They are capable of high peak torques, but caution is advised due to rapid temperature rise in the copper winding during high pulse loads.

Mechanical Data: The motors feature resolver feedback and comply with IP 65 standards, with IP-67 available upon request. The insulation system meets EEC LV Directive 73/23/EEC and 93/68/EEC requirements.

Motor Name Structure: The naming convention includes type, flange size, stator length, winding, feedback, power connector, brake, shaft key, and options. HDD denotes shaft motors, while ICM indicates internal coupling motors.

Holding Brake and Thermistors: Options include no brake or a holding brake. Protection is provided by thermistors, although they may not react quickly enough during high pulse loads.

Torque and Current: Torque is measured at a 90ºC temperature rise. The document provides a graph of short-term torque versus speed, indicating performance at various commanded currents.

Load Specifications: Maximum axial and radial loads are specified for shaft motors, with life expectancy set at 20,000 hours under specified conditions.

Important Notes: Users are cautioned about the limited permitted pulse time at high peak torques due to rapid temperature increases. Short pulses under 0.5 seconds are acceptable if the rms current remains below 7 A.

Duty cycle CurrentCurrent at 90°C temp rise, in Ampere rms. Torque Data were measured on an HDD14J-Pa series motor mounted on a vertical 450 x 375 x 30 mm steel plate in free air, with a winding temperature rise of 90°C and driven by a commercially available inverter. The HDD/ICM motors are capable of high peak torques. At very high peak torques the permitted pulse time is very limited as a high current in a very small motor causes rapid temperature rise in the copper winding. The protection thermistor will not react fast enough to protect the winding during high pulse loads. A 40A rms current...
