Amendment No. 2 to Schedule 13D

This Amendment No. 2, dated February 3, 2010, to Schedule 13D is filed on behalf of Richard Rappaport (the “Reporting Person”), and amends that certain Schedule 13D as previously filed by the Reporting Person with the Securities and Exchange Commission March 17, 2008 (the “Original 13D”), as amended on May 15, 2009 (“Amendment No. 1,” and together with the Original 13D, the “Schedule 13D”) relating to the common stock, $0.0001 par value per share (the “Common Stock”), of China Electric Motor, Inc. (formerly known as SRKP 21, Inc.) (the “Issuer” or “Company”), a Delaware corporation. This Amendment No. 2 is being filed to report a material change in the percentage of shares of Common Stock beneficially owned by the Reporting Person as a result of an increase in the number of outstanding shares of the Issuer’s Common Stock.

Unless specifically amended hereby, the disclosures set forth in the Schedule 13D shall remain unchanged. Capitalized terms used but not defined herein shall have the meanings set forth in the Schedule 13D.

Item 5 of the Schedule 13D is hereby amended and restated as follows:

Item 5. Interest in Securities of the Issuer

(a) The Reporting Person beneficially owns an aggregate of 1,268,257 shares of Common Stock, representing 6.3% of the outstanding shares of Common Stock (based on the number of outstanding shares beneficially owned by the Reporting Person as of February 12, 2010). The amounts of Common Stock owned by the Reporting Person disclosed in this Amendment No. 2 to Schedule 13D give effect to the 1-for-1.53846153846154 reverse stock split that became effective on January 22, 2010. The percentages used herein and in the rest of Item 5 are calculated based upon 19,994,743 shares of Common Stock issued and outstanding as of February 12, 2010.

(b) The Reporting Person has the sole right to vote and dispose of, or direct the disposition of, the 1,268,257 shares of Common Stock beneficially owned by the Reporting Person.

On February 10, 2010, the Reporting Person exercised warrants to purchase 100,303 shares of Common Stock at an exercise price of $0.000154 per share.
