Ordering Information
① Product series
KECM series servo motor
② Winding voltage
24 = 24VDC (for 100/200/400W)
48 = 48VDC (for 400/750/1000W)
220 = 220VAC (for 100/400/750/1000W, 1800/3800W available on request)
380 = 380VAC (for 1800/3800W)
* For servo motors operated in a vacuum pressure range of 10-10000 Pa, we recommend utilizing a low-voltage (24 or 48 VDC) winding motor to eliminate the risk of breakdown.
③ Rated power
100 = 100W | 200 = 200W | 400 = 400W | 750 = 750W | 1000 = 1KW | 1800 = 1.8KW | 3800 = 3.8KW
④ Feedback device
Blank = resolver. Incremental feedback. To achieve accurate positioning, it is necessary to implement a homing process, as the motor position is not recorded during power-off.
AE = geared multi-turn absolute encoder. With 17-bit single-turn resolution and 12-bit multi-turn. During power-off, the motor position is recorded. No back-up battery is required.
⑤ Safe brake
Blank = without brake
B = with brake

Description
Before being installed in vehicles, automotive wiring harnesses and connectors must undergo rigorous environmental simulation tests to verify their vibration durability under extreme temperatures. The KECM series high and low temperature servo motor plays a core role as an excitation or displacement drive in such testing equipment. As a professional high and low temperature servo motor, this series product can deliver rated torque stably across a wide temperature range of -60℃ to 120℃, and with high dynamic response characteristics, it can accurately reproduce complex vibration waveforms such as road load data, thereby realistically simulating the fatigue stress of wiring harnesses under different temperatures. Unlike conventional motors, the KECM series high and low temperature servo motor does not suffer from insufficient starting torque due to grease solidification at low temperatures, nor does it lose control due to insulation aging at high temperatures. Its robust structural design ensures reliability during long-term operation under alternating temperature conditions. When used for wiring harness vibration simulation, the high and low temperature servo motor typically requires closed-loop control with a high-precision encoder. The optional absolute encoder provides real-time position and velocity feedback, maintaining zero-point accuracy even after extended operation inside a temperature chamber. To prevent free fall of the vibration table during power outages, this high and low temperature servo motor can also be equipped with an optional brake mechanism, safely locking the load during standby or abnormal conditions. By incorporating the KECM series high and low temperature servo motor, test engineers can easily build a full-temperature-range wiring harness vibration simulation platform from -60℃ to 120℃, significantly shortening product development validation cycles. The excellent performance of this high and low temperature servo motor makes it suitable not only for wiring harness testing but also widely for environmental stress screening of other automotive components such as electronic assemblies and plastic parts, fully demonstrating the important application value of high and low temperature servo motors in reliability engineering.
Frequently Asked Questions
What temperature ranges can the KECM series servo motor support?
The KECM series servo motor offers different temperature rating codes (NTL1 to NTL4) supporting ranges from -40℃ up to +120℃, with customized options available for specific extreme high and low temperature requirements.
Why is a low-voltage winding recommended for vacuum applications?
For servo motors operating in a vacuum pressure range of 10 to 10,000 Pa, utilizing a low-voltage (24 or 48 VDC) winding motor is highly recommended to eliminate the risk of electrical breakdown under low-pressure conditions.
What feedback options are available for the KECM servo motor?
You can choose between a standard resolver for incremental feedback (requiring a homing process after power-off) or a geared multi-turn absolute encoder (AE) with 17-bit single-turn and 12-bit multi-turn resolution that retains position data without needing a backup battery.
Can the KECM series servo motor be used in vacuum chambers?
Yes, the motor supports an optional vacuum class designation (V3) designed to operate reliably in low pressure or vacuum environments down to 10-3 Pa.
How does the motor perform under extreme cold or hot temperatures?
Unlike conventional motors, the KECM series is engineered to prevent starting torque issues caused by grease solidification at low temperatures, and avoids control loss due to insulation aging at high temperatures, ensuring stable rated torque throughout its operational range.
Is there a safety brake option available for load protection?
Yes, an optional safe electromagnetic brake (Code B) can be integrated to safely lock the load during standby, power outages, or abnormal system conditions, preventing components like vibration tables from falling.
