660 W servo with holding brake — SH31001M01F2200
The SH31001M01F2200 is a Schneider Electric SH3 series servo motor with an integrated holding brake, rated for 660 W continuous power. It delivers a nominal speed of 3000 rpm when fed from a 480 V three-phase supply, and can run at lower speeds — 2500 rpm at 400 V three-phase, 1250 rpm at 230 V single-phase, or 625 rpm at 115 V single-phase — making it adaptable to different line voltages available on site. The holding brake provides 9 Nm of holding torque, enough to keep a vertical load stationary when the drive is disabled, without needing a separate mechanical brake. The motor uses natural convection cooling, so there is no fan to fail or collect debris — but the thermal budget depends on ambient temperature and duty cycle.
Absolute encoder and IP65/IP67 sealing
The absolute single-turn SinCos Hiperface encoder reports absolute position within one revolution at power-up, eliminating the need for a homing cycle on each start. This matters for applications where the machine must resume operation immediately after a power loss or emergency stop. The motor body is rated IP65, and the housing is IP67 per IEC 60034-5 — the shaft bushing also carries IP65. This means the motor withstands washdown environments typical in food processing, beverage filling, and pharmaceutical lines, where hose-down cleaning is routine.
Torque, inertia, and radial load limits
Maximum radial force at the shaft is 900 N at 1000 rpm, derating to 530 N at 5000 rpm. This sets the belt-tension or direct-coupling limit — exceeding it shortens bearing life. Maximum axial force is 160 N, so the motor should not be used to carry thrust loads without a separate thrust bearing.
The motor uses a standard 100 mm IEC flange (3.9 in) with a 19 mm smooth shaft and 6 mm keyway. The electrical connection is via a straight connector and a rotatable right-angled connector — both included, so the cable exit direction can be oriented to fit the cable tray or conduit path.
