Today we are taking a quick look at Yaskawa AC servo motors. Specifically, we will be reviewing the USAM, USAF, USAS, and USAD series of motors. These flange mounted, permanent magnet servos are direct drive motors intended for use with the Yaskawa CACR-SR servo packs.

Similar to the Yaskawa servo drives, the model number of the motor units describes the characteristics and ratings of the product. These AC servo motors are no different. After “USA”, the next character designates the motor series. This can be M, F, S or D. Following the series designation is the enclosure style. An ‘E’ signifies totally enclosed, self-cooled servo motors where a ‘K’ refers to an external fan-cooled motor. The letter following this designates the magnet type; either D (ferrite core) or M (rare earth). The motor output capacity and revision order follow.

Rated at 6kW, the M series has the largest possible maximum output rated motor. The S series has the smallest maximum output rating at 3.08kW. These motors can be rated as low as 0.15kW! In the model number, the 4th character after the dash specifies the feedback unit on the motor. Following this is either a 1, to denote tapered shaft, or a 2, to denote straight shaft. The remaining characters in the servo model names are used for additional specifications such as shaft seals, brakes or keyways.

2500SUSASEM-02AC to -30AC
1500USASEM-02AE to -30AE
1000USASEM-02AF to -30AF

The Yaskawa AC servo motors can be installed vertically or horizontally and can withstand an ambient temperature range from 0°C up to +40°C.

Compact and efficient, the Yaskawa AC servo motor series are high-quality motors that feature a high-power rating in order to allow for quick response. Run with the appropriate Yaskawa AC servo pack, these motors give stable control operation and high accuracy among a wide range of environments.
