INTRODUCTION SEM has continuously developed its range of servo products to best serve the latest industry requirements. The new HDM range of servomotors uses the long experience gained in the servomotor field to give cost effective performance. The HDM range has been specifically designed to provide optimal performance whilst remaining compact and cost effective. The high torque to inertia ratio allows fast acceleration and deceleration and rapid dynamic response. These motors are ideally suited for any high dynamic application where space constraints apply. WHY BRUSHLESS? The optimum...

GENERAL INFORMATION On receipt the motors should be inspected. Any damage found should be reported ENVIRONMENTAL PROTECTION All SEM brushless motors are protected to IP65 except at the shaft where the protection is IP64 with a shaft seal fitted. Protection Class Description IP65 Totally protected against dust. Protected against low pressure jets of water from all directions with limited ingress permitted IP64 Totally protected against dust. Protected against water sprayed from all directions with limited ingress permitted Where a toothed belt is proposed, the motors should be flange mounted...

GENERAL INFORMATION MAINTENANCE AND SERVICING BEARINGS All HDM servomotors are fitted with double shielded, single row radial ball bearings. Under normal conditions, no maintenance is required. Bearing Sepcification Frame ISO Code for Drive End ISO Code for Non-Drive End HDM82 6002 2Z 6002 2Z HDM105 6004 2Z 6003 2Z HDM142 6205 2Z 6004 2Z The bearings are selected to give a minimum of 30,000 hours life. Refer to the shaft loading graphs for further information. MECHANICAL It is recommended that a general inspection be made at regular intervals to check all bolts, nuts couplings etc to ensure...

GENERAL INFORMATION HOLDING BRAKES HOLDING BRAKE OPTIONS All brakes used on the HDM motors are constructed such that when in the power off state (brake engaged condition) the brake friction plate is forced into frictional contact with the rigidly fixed brake housing thus preventing the friction plate from rotating. These are primarily a holding brake e.g. to hold a load under a no voltage condition. However, the brake can also be used in some applications for emergency stopping. Connection should be such that when the motor is powered the brake is energized and the brake released. Under...

E.U. DIRECTIVES There are three main directives that affect applications incorporating servomotors. MACHINERY DIRECTIVE 2006/42/EC This directive applies to complete machines and SEM HDM servomotors are therefore exempt. LOW VOLTAGE DIRECTIVE 2006/95/EC This applies to all electrical equipment for use with a DC voltage of 75V to 1500V and AC voltage from 50V to 1000V. HDM brushless servomotors in the ranges, HRDM82, HDM105 and HDM142 conform to the EC directive. A certificate of conformity is available from SEM sales on request EMC DIRECTIVE (ELECTRO MAGNETIC COMPATIBILITY) 2004/108/EC The...
