C-LM helical servo geared motor without encoder
Properties of C-LM helical servo geared motor
- Compact and highly dynamic thanks to direct mounting of the gearbox on the servo motor without adapter and coupling
- Low-noise operation – thanks to helical gearing of the gearbox gears
Precise – constant backlash - No positioning errors – ratio in the form of a fraction
- Maintenance-free – no oil change required for gearbox sizes C0 – C5
- Operating position to be specified when ordering
- Ambient temperature from 0 °C to 40 °C (other temperature range on request)
- Filled with synthetic lubricant CLP HC ISO VG 150,
- Maximum permissible gearbox temperature (on gearbox surface) ≤ 80 °C
- Protection class IP65
- Output shaft sealing standard NBR.
- For duty cycles > 60% and higher ambient temperatures, radial shaft sealing rings made of FKM are recommended at the output.

Properties of LM servo motors without encoder
- Ideal replacement for asynchronous motors
- Higher energy efficiency compared to comparable IE4 asynchronous motors
- Energy efficiency IE5 according to IEC/TS 60034-30-2
- Significantly lighter and more compact than comparable asynchronous motors
- Higher acceleration capability than asynchronous motors
- More compact.
- Robust due to elimination of the encoder.
- Resistant to vibrations and shocks.
- Cheaper alternative to servo motors.
- Much more durable, as there is no electronics in the motor.
- Full control of speed and torque at low speeds and at standstill.
- Only a standard power cable without additional encoder cables or shielding.
- Wiring limited to the power supply connection cable
- Power plug connector freely rotatable with quick-locking system
- No cooling required at low rotational speeds.
- Speed deviation less than 1%
- Compatible with motor controllers – servo drives SB6, SC6, SI6.
- Positioning accuracy +/-1° on the servo motor shaft without encoder
- Protection class IP56
- Ambient temperature from -15 to +40°C
- Thermal motor protection – integrated PTC thermistor
- Rolling bearings with lifetime lubrication and non-contact sealing
- Radial shaft seals made of FKM
- The product complies with EU (CE), United Kingdom (UKCA) and cURus directives
