Feedback and brake — what the encoder and holding torque mean for axis design
The SH31001M01F2100 carries an absolute single-turn SinCos Hiperface encoder — this gives position at power-up without a homing move, critical for coordinated multi-axis lines where a loss-of-power restart must pick up the workpiece location immediately. The 9 N.m holding brake holds a vertical load on power-down; sized for a 9 N.m static torque, it prevents Z-axis drift during an E-stop or when the drive is disabled. The encoder is single-turn, so the absolute position range is one revolution — for longer travel the drive must track the turn count. The SinCos Hiperface protocol delivers 16-bit resolution per turn, giving 65536 counts per revolution, which is enough for most pick-and-place and packaging axes without a secondary encoder.
Speed-torque envelope across supply voltages
Nominal speed and torque shift with the supply: at 400 V three-phase the motor delivers 2500 rpm at 2.52 N.m; at 480 V three-phase it reaches 3000 rpm at the same torque. This means the same motor can serve a 3000 rpm line in a 480 V plant or a 2500 rpm line in a 400 V plant — the winding is designed for the wider voltage range, so no hardware change is needed for different regional supplies. Continuous power is 660 W, but the nominal output power varies: 790 W at 400 V three-phase, 930 W at 480 V three-phase. The continuous torque rating of 2.52 N.m at 400/480 V is the thermal limit; for short-duration moves the peak stall torque is 9.6 N.m, giving a 3.8× overload capability for acceleration or deceleration.
Mounting and environmental sealing for washdown or dusty lines
The motor body and shaft bushing are both rated IP65 per IEC 60034-5 — the housing seals against dust ingress and low-pressure water jets from any direction. This is the standard sealing for food-and-beverage packaging lines, conveyor washdown zones, and machining centres where coolant spray is present. The rotatable right-angled connector lets the cable exit point be rotated in 90° increments, which simplifies cable routing in tight enclosures or where the motor sits close to a machine frame. Mounting is to an international standard flange with a 100 mm flange size and a 95 mm centring collar diameter. The shaft is a smooth 19 mm diameter with a 6 mm keyway — standard for coupling to a timing-belt pulley or a flexible jaw coupling. The overall length is 199.5 mm, which fits within a typical 200 mm machine envelope.
